... there's a chatroom?
Must admit, I have been totally oblivous to the fact that it says "chat" in that menu.
I always think of chatting as 'live' typing on screen. Is the 'chat room' set up that way?
Otherwise it would be the same as the rest of this site, using 'replies' and waiting for the message to post.
I went on there when I first joined the forum a couple times but there wasn't anyone there. I would think it would come in handy if you are trying to arrange a meet-up or get a buy/sell deal done quickly.
Handy really in this sort of setting, as opposed to the old days say at the Yahoo chat etc where it was a bunch of kids with nothing better to do.
