I was shocked to see that there are no English-language Mobilizon servers. It seems like it may be an ideal secondary service for certain existing fediverse communities and was wondering if anybody here had considered it.
For those unaware, Mobilizon looks to fill the role of something like Facebook groups for the fediverse. I believe it is compatible with both Mastodon and Lemmy through the groups actor in the ActivityPub spec but provides additional functionality dealing with scheduled events and shared resources.
In theory you should be able to run this using existing fediverse accounts similar to how the new db0 wiki lets you log in with your lemmy credentials. Obviously not quite what you’re asking for but it is a step in that direction.
Long term I’m really looking to more explicitly modular services like Bonfire.
