I have added a flash based chat room at the bottom of the homepage. I think it looks and handles pretty well, so please feel free to take it for a test drive. If it looks like my regular visitors like it, it will replace the existing one.
When you log in, you will be in the Online Documentary 4 U Chat Room by default. There are, however, over chat rooms available there if you want to have a bit of a look around.
I am still getting my head around it, but I understand that you can use your existing IRC software to connect.
Your members can also access your chat room with any IRC client, mIRC, X-Chat, ircZ, Ircle, Conversation, Colloquy, and more. The server address is irc.everywherechat.com port 7000 or 6667.
