How can I get one of this medails (colore: green, yellow, red and orange). Must I visit the Club many times or what I do in the Club. Thanks when somebody can answer me this question in a short time.

You have to contribute to the site (videos, images and links are the best way) and people then have to click the green button that says 'fan of it?' (I like to call them 'likes'). Therefore the better it is the more likely someone will 'like' it. After a certain number of 'likes' you will get a green medal, then a yellow, then a red and finally orange. This can take a very long time. I believe you need around about 1600 'likes' to get red and I have no idea about orange. I try to help out by 'liking' everything I view but I don't know about others. Good luck :)
