Hello i have no idea if/how it goes to remove a clan. and i know it is kind off waste tc's but if it goes please tell me. to manage a clan is not my thing.

You could remove all members, and then you could quit.

Or, make someone else leader. Promote them, then leave.

Yeah i don't believe you can delete a clan, it can only die/become inactive. Do what WeooWeoo said and kick everybody and leave if it is dead.

yeah it will just join the pile of dead clans and that will be it, or if you don't even want to do that, give it to some random kid who is looking for a clan, inv them to your clan and promote them to leader, that is sure to make someone's day
