+Because CSS doesn't really support aspect ratios (despite a standard that says it does) you'll have a difficult time positioning and sizing many elements on the page.  The `--aspect-ratio` hack I've put into `static/global.css` does a decent job of creating a fake aspect ratio system without too many changes to your HTML.  You only need to add:
+
+```
+style="--aspect-ratio: 16/9"
+```
+
+And the magic CSS should do what you want.  It's a trick I've taken from [an article on CSS tricks](https://css-tricks.com/aspect-ratio-boxes/#using-custom-properties) that gives an excellent solution that doesn't require crazy changed to your CSS or HTML.  You can also use `16/9` or decimal notation `1.4`.
+
+Limitations
+===
+
+As you change the size of this demo you'll see the limitation of this method.  As the boxes shrink the text will explode out of the "box" that CSS has, or the boxes will cover other boxes. It's best to have only 1 or 2 elements that use `--aspect-ration` and test it at various sizes.

+This is a _very_ basic implementation of a calendar that you might use in a fancy date picker.  It does _not_ take into account the myriad of different date systems in the world, but it wouldn't be hard to change it to meet your needs.  Consider it a starting point for your own Calendar if you need one.

+The Callout is simply a way to focus the user on a piece of text they should see.  There's different levels of callout you can use:
+
+* `class="alert"` -- An alert style you can use to tell of impending doom. Change the variable `--red` or `--color-error` in the CSS to change it's color from the default monochrome.
+* `class="success"` -- For success messages. Change `--color-good` or `--green` to change it in the CSS.
+* `class="warning"` -- For warning messages. Change `--color-warning` or `--orange`.
+* `class="info"` -- For info messages. Change `--color-info` or `--yellow`.
+
+When I say "change color" I mean go into the file `static/monochrome.css` or `static/color.css` to change how it looks.

+Cards are used everywhere on the web, many times without you even knowing it.  They allow you to show an image or similar media, some text, then some buttons.  A variant of `Cards` is `Tiles` that are a horizontal layout of the same information.  I generally use `Card` when I want a large display of the image or video, and `Tile` when I want a small display with a thumbnail or icon.

+The `Carousel` is found mostly on landing pages and even then it's considered not very useful.  The problem with this UI component is it makes it difficult to navigate the images, and if it's automated then users will have a hard time accessing something you show them when it passes by.  If you're using it I suggest using it only on the landing page, and then if it auto-rotates have it stop when users touch it for the first time.

+The `Chat` is a small mini chat you might find on live streaming websites.  It's not full featured but the client and backend are simple enough that you can change them to do what you want.  To make it work you may need to look at `socket/chat.js` and make sure that's running correctly.  If you don't use `Chat` on your site then consider removing `socket/chat.js` and edit `client/stores.js` to remove all [socket-io](https://socket.io) references.  This will save you about 50k in the downloaded size of your app.

+The `Code` component simplifies displaying code with line numbers and letting people copy the code to their clipboard.  It will get the code from a URL, wrap it in a `<pre><code>..</code></pre>` block, and then convert each line to an inner `<span>` so it will receive a line number using CSS.
+
+The CSS that makes this magic happen is:
+
+<pre>
+<code data-language="css">
+pre code span::before {
+  counter-increment: line;
+  content: counter(line);
+  display: inline-block;
+  padding: 0 0.3rem;
+  margin-right: 0.5rem;
+  border-right: 1px solid var(--color-inactive);
+  min-width: 3ch;
+  text-align: right;
+  color: var(--color-inactive);
+  -webkit-user-select: none;
+  -moz-user-select: none;
+  -ms-user-select: none;
+  user-select: none;
+}</code></pre>
+
+This uses the `::before`` selector to add a line number counter to the front of each span, and then create a thin line. This is why you can use your mouse to select the lines of code but the _line numbers_ won't be selected (even if some browsers show you they are being selected).
+
+To make it easier on people it will also just copy the code when you click on it and then do a `Toast` alert.

+
+This changes the CSS using the variables in that block to alter their colors to darker versions.  Then in the JavaScript the theme is stored in the browser's local storage to remember it:

+The FairPay component is more of a demo than an actual component.  It shows how to use the
+`Paypal.svelte` and `BTCPay.svelte` components.  The `FairPay.svelte` implements a "pay what you
+want" style of payments.
+
+Why the $10 increments?  There's a form of credit card crime called "carding" where people with
+stolen numbers test their cards on any purchase that is $1.  They'll get large numbers of possibly
+valid credit cards and they need to test them.  The best way to test them is to attempt a very small
+purchase, and if the purchase works then they mark the card valid.
+
+If you allow people to pay any amount as a donation then carders will raid your purchase form and
+rack up $1 fraudulent charges.  That may not seem to bad, but your payment processor will then
+charge _you_ $15 or more to handle the charge back.  Even if you offer to refund the purchase and
+they do no work.  This means if you receive $100 of fraudulent charges you would owe $1500 in fees.
+
+The easiest way to prevent this is to simply only allow increments of $10.  $10 is too high for most
+carder testers, so this will deter them (at least until everyone does this).

+The `Flipper` shows two panels on the front and back of and lets you "flip" them around.  This is a
+decent way to restrict the user interface between two options, but it will most likely have problems
+with accessibility without some additional `aria` attributes.
+
+The technique uses the `transform-style: preserve-3d` to make sure that the browser treats it like a
+3D space.  Then it uses `transform: rotateY(180deg)` to do the flipping action.
+
+You finally need these two lines to maintain the back and front:

+```
+-webkit-backface-visibility: hidden; /* Safari */

+This demonstrates how to use the `FormField` component to construct forms with nicer error messages.  There are a lot of things you need to do for nice error messages on forms, and `FormField` handles most of them. You need to set variables for it, then place your input inside:
+
+```
+<FormField form={ form } field="subscribe" label="Want Notifications?">
+  <input type="checkbox" id="subscribe" name="subscribe" bind:checked={ form.subscribe }>
+</FormField>
+```
+
+All of the input fields work mostly the same but with Svelte you need to use `bind:checked={
+variable }` instead of `bind:value`.

+You can use the `Video` component to stream any HLS stream.  On Apple's Safari this works natively and doesn't require any additional code.  On other platforms you have to use the [HLS.js library](https://github.com/video-dev/hls.js/) in `static/js/hls.js` to decode and play the HLS protocol.

+
+   This demo won't work without you modifying it with an HLS stream (or other stream supported by the `<video>` tag. Change the stream variable in `client/bando/demos/LiveStream.svelte` to enable one.

+The LoggedIn component checks if the user is logged in by doing a GET to "/api/login" and if that API endpoint returns 401 or 403 it will perform redirects for you.  It updates the `$user.authenticated` Svelte store (from `client/stores.js`) and then as your app changes that setting it will adapt and display different content.

+Use this component to:
+
+1. Block a page's content from unauthenticated users.
+2. Redirect users to your a new location if they are not authenticated.
+3. Show a standard redirect page when it's redirecting.

+This is mostly only a demo because Twitter doesn't actually render JavaScript client
+side so it won't see these meta tags.  If you want this to work, put it on a page in
+<code>rendered/pages/</code> and don't Hydrate it.
+</span>
+</callout>
+
+You can create a special page/link for Twitter, Facebook, and LinkedIn that will render a summary+image for the page.  Uses its own preview-card feature [docs](https://developer.twitter.com/en/docs/twitter-for-websites/cards/guides/getting-started) while Facebook and LinkedIn use the [OpenGraph](https://ogp.me/) specification.  OpenGraph is much simpler, really only supporting things like links, images, etc.  Twitter's is more capable since it allows you to link to images, embed videos, live streams, and link to apps in Apple and Google stores.
+
+The component starts with a base set of attributes for OG and Twitter cards, which you can augment by simply updating the object used.  All the component does is walk through the `twiter` or `og` keys and create the necessary `<meta>` tag for the head.
+
+Svelte:Head Sort-of-Bug
+===
+
+One thing to keep in mind is if you place these `<meta>` tags directly in a page then they'll get duplicated on each page visit.  This is because Svelte is updating the DOM for the page, but seems to not consider the `<svelte:head>` as idempotent as other elements in the DOM.  The fix is to move all uses of `<svelte:head>` into a component so Svelte properly updates them on page changes.
+
+The code for `OGPreview.svelte` does this, which means you *do not* put it into a `<svelte:head>`.  Instead you do this:
+
+<pre><code data-language="javascript">
+&lt;OGPreview og={ og } twitter={ twitter} />
+</code></pre>
+
+Then `OGPreview` does everything for you.  If you run into this bug in your own development use the `client/components/HeaderOnce.svelte` component like this:
+
+```
+<HeaderOnce>
+<meta-tags-here>
+</HeaderOnce>
+```
+
+Those tags will then technically be in a "component" so they'll update as you change pages rather than get duplicated for each page.

+`SnapImage` creates a temporary image using SVG that looks _kind of_ like the incoming image, and
+when that image finally loads fades it into view.  This helps with _perceived_ render speed in the
+following ways:
+
+1. The aspect ratio of the image is placed before the page loads, reducing or eliminating render shift.
+2. A block of responsive SVG loads instantly which tricks the browser into fully rendering the whole page making it seem faster.
+3. The rendered colors look enough like the image for the brief time they're present that people percieve the image as loading faster even when it's not.
+
+By default `SnapImage` will use a set of random monochrome colors if none are given.  You can change the options used to generate the random colors by setting `random_options` like this:
+
+```
+random_options = {
+ hue: "monochrome",
+ "format": "rgbArray",
+ "luminosity": "random",
+ count: 10

+Layers with different opacity are a staple of digital compositing systems but weirdly CSS is terrible at it.  The stack/layer CSS in `static/global.csS` implements a simple method using `display: grid` to place elements into a single cell.  The CSS grid system will then correctly layer each element in a stack.  The elements also are set to `position:relative` so you can change their `z-index` to shuffle them around.  Alternatively, you can simply set one of the children to `class="top"` and that one element will be on top.
+
+
+If you don't set a `background-color` color then the layers will be transparent.  You can also use `opacity` to hide or fade the layers in the stack.
+
+
+The CSS that is making this work is below (but look in `static/global.css` to confirm it's still done this way.

+This is a CSS only component that simply provides a classic "tile" layout.  A tile seems to be organized with a left side that has an image/icon, a middle with content, and a right with buttons or other things.  You don't need Svelte to make this work, and actually trying to use Svelte ends up making it more complex than just using CSS. To see how you use this just look in `client/bando/demos/Tiles.svelte`.

+This demonstrates how to use the simple `Toasts` component, but it *also* shows how to use a function provided by a component in Svelte.  The trick is to realize that functions are variables, and that Svelte will let you _bind_ variables.  You then simply have to do:
+
+```
+let send_toast;
+```
+
+In your script, and in your use of the component (`Toasts`) bind it like this:
+
+```
+<Toasts bind:send_toast />
+```
+
+Now when the Toasts component is loaded it will set _your_ `send_toast` variable to the function so you can call it.  In your component then you simple do:
+
+```
+export const send_toast = () => {
+  // code here
+}
+```
+
+Which will export it like a variable, but set it to `const` so Svelte doesn't complain that you aren't using it.

+The `Video` component can handle both static video downloads and streaming using HLS.  On platforms that support HLS video it will use the native `<video>` tag, but if the platform doesn't support it then it will fall back to [HLS.js](https://github.com/video-dev/hls.js/).  Internally it uses the `client/fsm.js` code to keep everything straight while it juggles all the byzantine errors you have with videos.
+
+Most of the options exported by `Video.svelte` make sense but the `aspect_ratio` setting is probably one you'll want to adjust if your videos aren't 16:9.  This setting uses the CSS in `static/global.css` that uses `--aspect-ratio` to make sure the container holding the video stays at the correct aspect ratio.  Without this setting the video's container will do weird things at different screen sizes.
+
+This demo also shows how the countdown timer works with `starts_on` which is useful for live streaming situations where shows start at specific times.

+The [WebTorrent](https://webtorrent.io) project provides a way for websites to
+share the bandwidth load with the users viewing content. It works on almost any
+content, but the first thing I I implemented is for Video.
+
+This will most likely *only* work if you have your server on `localhost:5001` since the torrent file is configured for that.  Also, the default `npm run dev` will run the simple tracker implementation found in `services/tracker.js`.  If you want to generate the torrents again then run:
+
+```
+sh scripts/mktorrents.sh sample.mp4
+```
+
+It uses the [mktorrents](https://github.com/pobrn/mktorrent) to generate the torrent since it is faster.  Be careful of the WebTorrent specific options I use in the ``services/mktorrents.sh`` that are needed for WebTorrent to understand the torrent:
+
+* `-p` -- Sets the private flag.  This isn't needed for WebTorrent but is
+  needed if you want to add extra protections to people accessing your content
+  only after they log in.
+* `-l 15` -- Sets the piece length to 15.
+* `-w localhost:5001` -- Sets an initial web URL to use as a source.  You
+  should remove this if you want them to only go through the tracker and other
+  users.
+
+Download Link
+===
+
+If you want to let people download the video then add the `download={ true }` property.  This demo sets that option so you can see how it works.

+      <li><b>No Authority without Consent</b> -- You can request an admin be removed if you feel they're doing a bad job.  If Zed is not managing things well you can tell him and he'll change his management style. No, you can't remove Zed.</li>
+      <li><b>No Public Shaming</b> -- You will not be publicly shamed.  If you're not following the code of conduct you will be <b>privately</b> reminded of the rules, and told exactly how your behavior is impacting others.  If you block the admins though then, well, I guess we have to remove you until you're willing to talk privately.

+
+    <h1>Code of Conduct</h1>
+
+    <p>Please be respectful by following these four simple rules of behavior:</p>
+
+    <callout>
+    <ol>
+      <li><b>No Drama</b> -- Don't cause drama with others on the server. That includes racism, sexism, harrassing, stalking, or anything that causes someone...drama.</li>
+      <li><b>No Hacking</b> -- Don't hack, exploit, or access anything you don't own.  If you find an exploit in this server tell Zed immediately.</li>
+      <li><b>No Free Therapy</b> -- There is no unpaid emotional labor allowed on the server. You paid for a programming course, not a therapy session.  It's unfair to everyone else to make them responsible for your mental health. If you're having strong emotions find someone you trust and talk to them about it, or just keep working on the code.  Usually if you just keep trying to solve it you'll find the solution and feel better.</li>
+      <li><b>No Enforcing The Rules</b> -- You paid to take a class, not be an admin.  Only Zed (or a <b>well known admin</b>) is allowed to remind people of these rules.  If someone is causing drama, hacking, or demanding free therapy then simply DM Zed and block them.</li>
+    </ol>
+    </callout>
+
+    <h1>Not Essential to the Course</h1>
+
+    <p>Finally, this important warning about access to Discord:</p>
+
+    <callout class="warning">
+      <p><b>Access to the Discord server is not part of the product you purchased.</b>  If you are removed from the server you will still have access to the content you paid for, email help, and other services.  It's entirely voluntary and not essential to finish the course.  </p>

On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.\n *\n * When the task execution (`tick` method) is called in re-entrant way this is detected and\n * we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further\n * task processing on the next main loop iteration (also known as \"next tick\" in the Node/JS runtime lingo).\n */\nexport default class TaskLoop {\n  private readonly _boundTick: () => void;\n  private _tickTimer: number | null = null;\n  private _tickInterval: number | null = null;\n  private _tickCallCount = 0;\n\n  constructor() {\n    this._boundTick = this.tick.bind(this);\n  }\n\n  public destroy() {\n    this.onHandlerDestroying();\n    this.onHandlerDestroyed();\n  }\n\n  protected onHandlerDestroying() {\n    // clear all timers before unregistering from event bus\n    this.clearNextTick();\n    this.clearInterval();\n  }\n\n  protected onHandlerDestroyed() {}\n\n  /**\n   * @returns {boolean}\n   */\n  public hasInterval(): boolean {\n    return !!this._tickInterval;\n  }\n\n  /**\n   * @returns {boolean}\n   */\n  public hasNextTick(): boolean {\n    return !!this._tickTimer;\n  }\n\n  /**\n   * @param {number} millis Interval time (ms)\n   * @returns {boolean} True when interval has been scheduled, false when already scheduled (no effect)\n   */\n  public setInterval(millis: number): boolean {\n    if (!this._tickInterval) {\n      this._tickInterval = self.setInterval(this._boundTick, millis);\n      return true;\n    }\n    return false;\n  }\n\n  /**\n   * @returns {boolean} True when interval was cleared, false when none was set (no effect)\n   */\n  public clearInterval(): boolean {\n    if (this._tickInterval) {\n      self.clearInterval(this._tickInterval);\n      this._tickInterval = null;\n      return true;\n    }\n    return false;\n  }\n\n  /**\n   * @returns {boolean} True when timeout was cleared, false when none was set (no effect)\n   */\n  public clearNextTick(): boolean {\n    if (this._tickTimer) {\n      self.clearTimeout(this._tickTimer);\n      this._tickTimer = null;\n      return true;\n    }\n    return false;\n  }\n\n  /**\n   * Will call the subclass doTick implementation in this main loop tick\n   * or in the next one (via setTimeout(,0)) in case it has already been called\n   * in this tick (in case this is a re-entrant call).\n   */\n  public tick(): void {\n    this._tickCallCount++;\n    if (this._tickCallCount === 1) {\n      this.doTick();\n      // re-entrant call to tick from previous doTick call stack\n      // -> schedule a call on the next main loop iteration to process this task processing request\n      if (this._tickCallCount > 1) {\n        // make sure only one timer exists at any time at max\n        this.tickImmediate();\n      }\n      this._tickCallCount = 0;\n    }\n  }\n\n  public tickImmediate(): void {\n    this.clearNextTick();\n    this._tickTimer = self.setTimeout(this._boundTick, 0);\n  }\n\n  /**\n   * For subclass to implement task logic\n   * @abstract\n   */\n  protected doTick(): void {}\n}\n","/**\n * @module BufferHelper\n *\n * Providing methods dealing with buffer length retrieval for example.\n *\n * In general, a helper around HTML5 MediaElement TimeRanges gathered from `buffered` property.\n *\n * Also @see https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/buffered\n */\n\nimport { logger } from './logger';\n\ntype BufferTimeRange = {\n  start: number;\n  end: number;\n};\n\nexport type Bufferable = {\n  buffered: TimeRanges;\n};\n\nexport type BufferInfo = {\n  len: number;\n  start: number;\n  end: number;\n  nextStart?: number;\n};\n\nconst noopBuffered: TimeRanges = {\n  length: 0,\n  start: () => 0,\n  end: () => 0,\n};\n\nexport class BufferHelper {\n  /**\n   * Return true if `media`'s buffered include `position`\n   * @param {Bufferable} media\n   * @param {number} position\n   * @returns {boolean}\n   */\n  static isBuffered(media: Bufferable, position: number): boolean {\n    try {\n      if (media) {\n        const buffered = BufferHelper.getBuffered(media);\n        for (let i = 0;

+       *
+       * Since the position of overwriting tokens (token in `redef` that overwrite tokens in the copied language)
+       * doesn't matter, they can technically be in any order. However, this can be confusing to others that trying to
+       * understand the language definition because, normally, the order of tokens matters in Prism grammars.
+       *
+       * Therefore, it is encouraged to order overwriting tokens according to the positions of the overwritten tokens.
+       * Furthermore, all non-overwriting tokens should be placed after the overwriting ones.
+       *
+       * @param {string} id The id of the language to extend. This has to be a key in `Prism.languages`.
+       * @param {Grammar} redef The new tokens to append.
+       * @returns {Grammar} The new language created.
+       * @public
+       * @example
+       * Prism.languages['css-with-colors'] = Prism.languages.extend('css', {
+       *     // Prism.languages.css already has a 'comment' token, so this token will overwrite CSS' 'comment' token
+       *     // at its original position
+       *     'comment': { ... },
+       *     // CSS doesn't have a 'color' token, so this token will be appended
+       *     'color': /\b(?:red|green|blue)\b/
+       * });
+       */

+
+      /**
+       * Inserts tokens _before_ another token in a language definition or any other grammar.
+       *
+       * ## Usage
+       *
+       * This helper method makes it easy to modify existing languages. For example, the CSS language definition
+       * not only defines CSS highlighting for CSS documents, but also needs to define highlighting for CSS embedded
+       * in HTML through `<style>` elements. To do this, it needs to modify `Prism.languages.markup` and add the
+       * appropriate tokens. However, `Prism.languages.markup` is a regular JavaScript object literal, so if you do
+       * this:
+       *
+       * ```js
+       * Prism.languages.markup.style = {
+       *     // token
+       * };
+       * ```
+       *
+       * then the `style` token will be added (and processed) at the end. `insertBefore` allows you to insert tokens
+       * before existing tokens. For the CSS example above, you would use it like this:
+       *
+       * ```js
+       * Prism.languages.insertBefore('markup', 'cdata', {
+       *     'style': {
+       *         // token
+       *     }
+       * });
+       * ```
+       *
+       * ## Special cases
+       *
+       * If the grammars of `inside` and `insert` have tokens with the same name, the tokens in `inside`'s grammar
+       * will be ignored.
+       *
+       * This behavior can be used to insert tokens after `before`:
+       *
+       * ```js
+       * Prism.languages.insertBefore('markup', 'comment', {
+       *     'comment': Prism.languages.markup.comment,
+       *     // tokens after 'comment'
+       * });
+       * ```
+       *
+       * ## Limitations
+       *
+       * The main problem `insertBefore` has to solve is iteration order. Since ES2015, the iteration order for object
+       * properties is guaranteed to be the insertion order (except for integer keys) but some browsers behave
+       * differently when keys are deleted and re-inserted. So `insertBefore` can't be implemented by temporarily
+       * deleting properties which is necessary to insert at arbitrary positions.
+       *
+       * To solve this problem, `insertBefore` doesn't actually insert the given tokens into the target object.
+       * Instead, it will create a new object and replace all references to the target object with the new one. This
+       * can be done without temporarily deleting properties, so the iteration order is well-defined.
+       *
+       * However, only references that can be reached from `Prism.languages` or `insert` will be replaced. I.e. if
+       * you hold the target object in a variable, then the value of the variable will not change.
+       *
+       * ```js
+       * var oldMarkup = Prism.languages.markup;
+       * var newMarkup = Prism.languages.insertBefore('markup', 'comment', { ... });
+       *
+       * assert(oldMarkup !== Prism.languages.markup);
+       * assert(newMarkup === Prism.languages.markup);
+       * ```
+       *
+       * @param {string} inside The property of `root` (e.g. a language id in `Prism.languages`) that contains the
+       * object to be modified.
+       * @param {string} before The key to insert before.

+I Am Markdown
+===
+
+This is a simple Markdown component demo:
+
+1. It uses the [marked](https://marked.js.org/using_advanced) library.
+2. You can set options={} settings for marked.
+3. It renders raw HTML so be careful letting people use this directly on your site.
+
+You can <a href="/">link with a-tags too</a>.
+
+You can also write tags directly like this:
+
+<pre>
+<code>let x = 1 + 1;</code>
+</pre>

If you make a contribution you must have the right to contribute this Contribution under CC-BY, either through ownership of the copyright, because the Contribution is in the public domain, or through a license that grants you this right consistent with these Terms. If your Contribution is protected by copyright, then unless it is licensed under CC-BY or under a license which grants you the right to contribute it under CC-BY, you must not provide the Contribution to BIG. You warrant, represent, and assert that you have the right to provide the Contribution, that no Contribution violates or infringes the rights of any third party, including copyright, trademark, privacy, publicity, or any other personal or proprietary rights, that the Contribution does not constitute confidential or trade secret information, and is not defamatory, libelous, or unlawful. You can otherwise license your own copyrighted Contribution any way you like, or not at all. But when you provide a Contribution to the Sites, you are explicitly granting BIG a license under CC-BY without regard to any other licenses you apply to your Contribution.</p>\n<p>B. You understand and agree that the Sites and Content are a collective work or compilation under the copyright laws of the United States and other countries, and that the Sites and Content do not constitute a joint work under copyright law.

You hereby designate BIG and its contributors as the sole “Attribution Party” under Section 4(b) of the CC-BY license to attribute your Contribution as part of the collective Content of the Sites. With this designation, you release BIG from the obligation to specifically attribute your Contributions to you.</p>\n<p>D. You understand that the CC-BY license under which you provide a Contribution allows BIG and its licensors to use your Contribution for any purpose.</p>\n<p>E. You agree that any source code Contribution to a project hosted on the Sites will be contributed under, and subject to the posted license of that project. You acknowledge that you are responsible for including all copyright notices and licenses for your Contributions. Should you fail to include these notices and licenses, you assume all risks of failing to do so, including the possible loss of your rights to your Contributions.</p>\n<p>F. BIG may, but is not obligated to, review your Contributions. BIG may refuse to accept, or delete any Contribution that, in its sole discretion, BIG determines to violate these Terms, be illegal or objectionable, violate the rights or threaten the safety of others, deems not to fulfill the purpose of the Sites, or for any other reason. BIG may, in its sole discretion, terminate or suspend your registered account if your Contribution violates the Terms. Acceptance of a Contribution does not constitute an endorsement or sponsorship of the Contribution by BIG.</p>\n<p>G. You hereby grant BIG a royalty-free, perpetual, irrevocable, worldwide, non-exclusive and fully sub-licensable right and license under your intellectual property rights and under the terms of the CC-BY license, to reproduce, modify, adapt, publish, translate, create derivative works from, distribute, perform, display and use your Contributions in whole or part, and to incorporate them in other works in any form, media, or technology now known or later developed, for the purpose of providing the Sites, even in the event that you have subsequently deleted the Contribution. You agree that you alone are responsible for creating backup copies of your Contribution.</p>\n<p>H. If you delete your Contribution, the CC-BY license under which you provided your Contribution will remain in full force.
