If no other users online, Public chatroom is displayed twice.

Hi.

There's a small bug that displays the Public chat room twice if no other user is online. It's because, in your JS, you append the "No users" item to a list, expecting it to be a <li>. However, the way you render it server side is as a whole new list. This confuses JS on subsequent re-renders of the chat room list.

The fix is pretty easy though, patch coming up.
