There are quite a lot of places where you can talk to other fans. But erm... there are often empty :
IRC
#ut on dalnet : THE best place to talk about Unbelievable Truth (and lots of other things) I think. The best way to connect to this channel is to use mIRC, vIRC, Microsoft Chat or any other IRC software. But if you can't you can try (it doesn't always work) to go to http://www.dalnet.com or http://www.dal.net (and then click on chat)
ICQ
Almost Here an ICQ group of nice people. If you use ICQ, please add yourself to this group.
Web chats
"The green room" on The Unofficial Truth
