Go to your User CP. There should be something saying K.O.A.T.T.A. on the left. Move your mouse over all the way to the right. Your mouse should be on a little circle next to "join usergroup". You click on that and then go down and click "ok" or something like that. Then you have to wait for somebody to approve ya. Then, well, you're a member.

I probably didn't explain that well, though, did I?

P.S. If you have any other questions or just need a better answer I suggest PMing toontown dawg or Little_Romeo.
