Yes, anyone could tham gia your club, if bởi that bạn mean becoming a người hâm mộ of it. It's not possible to restrict any fanpop user from becoming a người hâm mộ of any club on Fanpop. Of course, các câu lạc bộ aren't owned bởi any particular user, even if that user created the club, so it's not really "your" club any thêm than the fanpop Users club is "my" club.
