How do tu leave clubs?

go to your profile
clubs
click on the x
done~

Legimate question! I had a hard time figuring it out, too.
Go to your perfil page. Click on "My Clubs" (The título that appears above all of your clubs). Find the club tu want to leave, and click siguiente TO the icon. A "X" appears in the parte superior, arriba right corner. Click it, and fanpop will remove tu from that club. Hope this helps!

There are two ways:
1.Go to your perfil and go to Clubs. A lista of your clubes will appear. There'll be a small cruzar, cruz on the parte superior, arriba right corner of each box. Click on it.
2. Go to the category the club belongs to - TV, Characters, Literature etc. Scroll through those til tu find the club. There'll be a red box saying "leave" beneath its icon. Click on that.
