Saying in advance that this feature exists in many forums, the question is: is it the shoutbox really needed or useful in your opinion? I say so particularly because, despite of the warning about "no support in the shoutbox", many people ignore it. The rest of the messages are what they are. In all of this, there's a lot of space in the most important place of the forum taken by the shoutbox itself. As I said, I know that many forums has this feature but this fact does not change the... facts. It'll be interesting, if any of the admins would like to do, to launch a poll about that.
