I have a number of Lemmy instances meant for discussion groups around specific topics. They are not being as used as I expected/hoped. I would like to set them up in a way that they can be owned by a consortium of different admins so that they are collectively owned. My only requirement: these instances should remain closed for registrations and used only to create communities.
This is not federation anymore, but an entirely different architecture. Nostr works like this, but it also has its flaws.
