Go to Fanpop's main page (click on the ファンポップ logo on the 上, ページのトップへ left of your screen, または type in the address www.fanpop.com). Click on the large green button on the 上, ページのトップへ right which says Create a New Club.
If that button doesn't appear for you, this means that あなた haven't been a ファンポップ member for long enough to create a club. New members have to be here for a few months before they can start making clubs. It's supposed to be an anti-spam measure.
