Allowing multiple users to join a chatroom (using Django, Socket.io and node.js)

I followed this tutorial and I created my own database, etc. I was able to run the above example successfully but I realized, it's just the barebones of what a chat encompasses.

Has anyone actually implemented a multi-user chat room with Django, Socket.io and Node.js?

Looking through the code, I essentially created a superuser/admin and now I can log in and log out. However, how do I create a log in for anyone to use to implement the chat and how do I get them to join the chatroom?

Thanks in advance.

Any direction to a tutorial, documentation or personal experience would be great.
