A chat room would be interesting on here, but knowing these forums, the chat room would be constantly filled with n00bs waiting for a female to enter the room, so that they can flirt with her. Ya, that's how I imagining it going down.
Chatrooms would cost more money and whats wrong with these forums? Its better then a chatroom. Even if they did make a chatroom, people wont post at the forums anymore they would all be in the chatroom.
Adding a chat wouldn't cost money....But yuh, it's a bad idea. Every forum that I know that has a chat, there's never anybody in it, and if there were, there wouldn't be a use for any fourm besides the GFX/Media/Babes forums.
