Most people are just going in, checking it out and leaving it according to the server. You guys should get together and schedule chats or something. Otherwise it'll take a while before people start regularly chilling in there. I've dealt w/ chat rooms before, that's generally how they go even with pro wrestling which is more popular than MMA, and my pro wrestling stuff online is much bigger than my MMA stuff so there's more promotion to it. So it'll take time to catch on by itself, but most people when there's a ton on the forums or a good argument going, should just say alright - get your ass in the chat room let's battle this one out with instant communication.
