The chatroom page has the wrong address, the right one would be:

http://embed.mibbit.com/?server=irc.cyberbrats.org&channel=%...

if you use a dedicated client:

irc://irc.cyberbrats.org/#Mainroom

address: irc.cyberbrats.org

channel: #Mainroom

The chatroom is up and running, at least for the moment.

so come and enjoy while it lasts.
