Yes, anyone could যোগদান your club, if দ্বারা that আপনি mean becoming a অনুরাগী of it. It's not possible to restrict any ফ্যানপপ user from becoming a অনুরাগী of any club on Fanpop. Of course, সংগঠন aren't owned দ্বারা any particular user, even if that user created the club, so it's not really "your" club any আরো than the ফ্যানপপ Users club is "my" club.
