Well, I'm pretty sure あなた 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 質問 and 回答 being posted, 写真 and 動画 being added, and a lot more. あなた may get a lot of notifications depending on how active the club is. And why are あなた asking this here?
