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 Von other users. So just Abschicken a lot of good (Not broken, spam, inappropriate, oder duplicate) content to a spot and if people like it, they'll Fan it. And sooner oder later if Du 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 Medaillen who've only gepostet 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 Du how many things Du must contribute to a club, except the F4, and I do not think they will be telling anyone anytime soon.
I'm sure Du asked this Frage because Du want a medal. All I can tell Du is, contribute a lot. But don't add Bilder that have already been added, Videos that have already been added. Make a bunch of good, thought out picks, add articles, links, the works. If Du add good content, people will Fan your stuff. This will help Du 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 Du find content that everybody likes and that hasn't already been submitted. For instance if your Favorit TV couple has their first hug oder KISS and Du see nobody else has Abgeschickt a picture of it, and Du have a picture Abschicken it to their fanpage, chances are that Fans are looking for that and will view and Favorit it a lot, although it helps if the spot is really active too, so Mehr people will see the picture.
