How did you got your medal ?

You just have to add content to the club: images, videos, articles and the like. If they're good quality stuff, people will fan it and eventually you'll get a medal. It takes a while though, so you have to be patient.

It takes awhile (a long while, really) but if you contribute enough to a club you'll eventually get one.

I got a green one for the Disney Princess club. idk how i got it at all! The one day, i had no metals, and then the next time i went on this site, BOOM! it was there!
