Sunbeam City is a Libertarian Socialist and solarpunk community. It is run and managed by the Sunbeam City cooperative! Check out our Matrix chatroom and wiki if you're interested. But you don't have to be a member of our cooperative to use the instance. Just sign up to the left and join in! We also have a sister Pleroma instance at Lunarpunk Space. The rules for our Mastodon instance can be found here.
Mastodon is a social network based on open web protocols and free, open-source software. It is decentralized like e-mail.
