Yesterday, the user clubs were introduced. A neat (albeit a bit chaotic) idea, but since it appears to be pretty difficult to leave a user club once you're in it, or the manager of the club doesn't want to remove you, I think it should be possibly to leave a club. Maybe it could be like the 'end friendship' button? When you go to the members page of the club, you will see a red X beneath your name where you can terminate your membership of the club.
