I'm gonna try to get involved!
Downloaded the Riot.im client from F-Droid and set up a Matrix account (username/password->email confirmation) so I can follow the new thread @liaizon started for figuring out how to hand instance administration over to the collective.
There's a Discourse thread as well: https://sunbeamcity.autonomic.zone/t/temporary-transfer-of-sunbeam-city-admin-rights/68
And of course people can talk to each other about any ideas they have. I'm not particularly interested in wielding authority as a rule, and I don't have any special power, so I can't promise any action, but I'll offer this thread as one place for people to mention the ideas/thoughts they have for the sake of modeling what I hope to encourage.
Sunbeam City is a Libertarian Socialist solarpunk instance. It is ran democratically by a cooperative of like-minded individuals.
