How to join a club on fanpop?

Well, I'm pretty sure you just press the green button on the right that says "Become a fan." Then you'll be notified in the place that says "my updates" of things that happen in the club, such as questions and answers being posted, photos and videos being added, and a lot more. You may get a lot of notifications depending on how active the club is. And why are you asking this here?
