I found this plugin on another forum I visit frequently, and I really think it would help everyone how here on what to talk about before etching thier words into e-stone. It's called QuickChat, and I believe it's still in either alpha or beta. It works great though, allowing whichever forum or website you are on to create an IRC like chatroom for that particular website. It might even cut down on obligitory newb questions, though I don't know. Enjoy!
