Sometimes you have to keep trying and trying to connect to a server when it is full. It can get rather annoying very quickly. So, there should be an add-on that fixes it. The add-on should be client-sided, of course. If a server is full, and you try to join it, but fail, instead of just saying "this server is full" and having 1 button, "ok", there should be a second button that says "auto-join". When clicked, the add-on will automatically detect when the server has space for another player to join, and automatically connects you to it. Even if you are in another server, it will automatically connect you to it. It will disconnect you from the server you are currently on without prompting you.
Of course, you should be able to disable this after you do it. A chat command and a button on the server list to disable it would be neat, because, let's say you find a better server- you don't want to auto-join the full one, you want to stay on that other server. So you disable it.
