Nobody knows. But I like it better that way, because I like the surprise of getting a medal. It wouldn't matter how much content you've submitted, anyway, because it needs to be fanned enough kwa other users. So just submit a lot of good (Not broken, spam, inappropriate, au duplicate) content to a spot and if people like it, they'll shabiki it. And sooner au later if wewe stay active at the spot, you'll get a medal.
Seriously. No one really knows how the medal system works. But I've seen people with medali who've only ilitumwa ten items while some people have posted, like, a million things to one club.
The medal system is a mystery to everyone on fanpop. No one can tell wewe how many things wewe must contribute to a club, except the F4, and I do not think they will be telling anyone anytime soon.
I'm sure wewe asked this swali because wewe want a medal. All I can tell wewe is, contribute a lot. But don't add picha that have already been added, video that have already been added. Make a bunch of good, thought out picks, add articles, links, the works. If wewe add good content, people will shabiki your stuff. This will help wewe get a medal. So, get contributing, and you'll be sure to have a medal soon enough!
I don't think there's a certain number, but it helps if wewe find content that everybody likes and that hasn't already been submitted. For instance if your inayopendelewa TV couple has their first hug au kiss and wewe see nobody else has imewasilishwa a picture of it, and wewe have a picture submit it to their fanpage, chances are that mashabiki are looking for that and will view and inayopendelewa it a lot, although it helps if the spot is really active too, so zaidi people will see the picture.
