Why isn't there a alisin button in my own presinto and clubs?

Once a club has been created, it doesn't just belong to whoever created it. It also belongs to other members, and to Fanpop in general. That's why a club can't be deleted. Even if you've Nawawala interest in it, there might be others here who like the topic and might want to join.

I think it might be possible to leave a club once you're not the only member, so if others have already joined this might be your best bet. Otherwise, you can ulat the club if it's a duplicate or inappropriate, and get it deleted that way. You can't ulat it for deletion just because you now think it's a stupid topic for a club, though.

presinto are the same way, belonging to all of Fanpop and not just you. I think it's possible to edit/delete presinto for a few minutos after creation, but not later. Otherwise people would just spitefully alisin any poll whose results weren't going the way they wanted.
