[IcyBoards] Looking for a Chatbox

[aven wolfsong]

Basically, I would like to find a shoutbox/chatbox that has dark grey background and lighter grey or white text. I have a super stupid brain so easy instructions to install would be ideal, as I have tried two different ones I have found and cannot understand the broken English. I would prefer simple, nothing flashy, just something that can serve as a real time message system. I would really appreciate it. My members are about to mutiny! lol
