As of a couple days ago, you can sign up for this instance directly at mastodon.mania.systems instead of having to be invited. Still requires admin approval, but .. yknow. I don't sleep.
Nextcloud is now the same - directly register at docs.mania.systems for an account.
Working on making the same changes elsewhere where I can.
Mania Systems a retro-futurist themed community for independent, underground, and non-traditional artists and creatives who want to share their work, meet each other, and collaborate, all in a safe space. We specifically try to build for the intersections of being queer, being chronically ill or disabled, being neuroatypical, and being mixed-race or brown - because that's who we are.
