Irc Chat!!!
After reading a closed thread and some pretty nasty replys i really think person to person would be best, after all, its one person reply to your post that you want to talk to, just look at my old Unlimited Prophanging thread ( or what ever i called it ) Miderror and my self sent replys back and forth, we now E-mail and ICQ chat.
My reason for asking for it is when someone replys, you can just wack these ideas back and forth very quickly.
The same style as the MP3 downloaders. Also very handy for those silly things you want to ask one person, but it doesnt warrent a thread, i know the current PM is the best way for this at the moment.
It could be an option wether to have this running or not.
For bigger chats, it would be better if it was an event type thing and then it can be morederated, ie ( tonight, talk to ******* the rep for X-Brand ) ( or tonight super star flyer ******* will take your questions ) like those internet chats you get after some TV programs
