we have (or at least I have) toyed with this idea, however to have a chat you need millions of hits or else you chat room has no one in 99% of the time, making it look bad. IF we had a steady diet of about 5 people in it at all times we would probably launch one, but until then, it is something just on the radar. Now, if you know a million people that want to come to the forums and start talking then I will launch it tomorrow :)
