Basically, by being an active member of a club and contributing things which others like: 1. Getting the links, articles, Обои and Видео you've added fanned 2. Answering lots of questions, Опросы etc. 3. It's easier to get Медали in еще active клубы than dormant ones.
I don't think there's a set number of Фаны или contributions. The system's pretty random. Sometimes it doesn't really make sense.
