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.
