I have connected to all of the chatrooms I could find in the forum. All of them seem to be empty, I was in one for 4 days (this was two weeks ago, just before I got zbrush) and there were two people who never spoke a word (I think they were bots)
Anyhow. Is there any current chat room set up? If not I am webmistress to a few sites and could easily set one up on a server I use for my other chats, as well as a java client on a page for those who do not have an irc client of their own to use.
If there is no chats currently and people would like me to set one up post here and I will kick one up in a few hours / days. Depends on the responses.
