Can't join a chat room when running the demo

I can't join a chat room when I visited the chat application demo at http://clankchat.tabletopr.com/

There is a join button, but no rooms are listed.

The chat worked but I was not able to change the username!!!

The Demo Chat no working. Send undefined nickname and undefined message.

I tried to connect two clients, but none see each other's messages (even "undefined:undefined).
