If you're the creator of a club and accidentally remove yourself, you can reach out to Clubhouse Community Support - we will investigate and reinstate on a case-by-case basis. Please select "Club, Show & Event questions". The more details you can provide, the easier it will be for us to help!
If you are a club admin, leader, or member, you will have to request to rejoin the club so the creator or another admin can reinstate you.
