I think what hes trying to say is...
having the chat window always on top.. so its on top of the game..
Then to stop it geting in the way, have it seethrough.. only showing the text.. so therefore you can see what sstill happening in the game.
But that could probably be done by a clear seethrough skin?
and also sumthing to make chat windows always on top. wich i still havnt found
