If a club is still pending, then it'll be listed in the "Pending clubs" section that's linked to the Главная page.
If it's a full club though, if Ты go to a certain category of clubs, for example, the "Celebrities" category where it lists all the клубы in that category, only full клубы are listed there, so pending клубы won't be.
I think a club has to get at least several hundred members to not be pending anymore, the fewest number of Фаны I've ever seen for a full club was two hundred-something.
i cant actually think of anything that changes once its a full club and i think the f4 can actually promote spots..but i cant remember where i read that, so i might have been imagining things. the process i am guessing is some sort of secret formula like the medal formula..something along the lines of X*links+activity*Y*magic fanpop*elves doing their work-cookies+images
