This 问题 has been asked almost every week for as long as I've been on here. Go to the 首页 page, and scroll down until the right side 你 see a 列表 of the club options. above them, it will have a tab that says make a new club. Hope this helped.
Only if it's your club can 你 change it. Then 你 would go to the little 图标 right 下一个 to the 图标 where 你 can 报道 或者 invite 老友记 to the club. Then 你 can add your banners and 图标 for the club.
