I run a gitea server, primarily for myself and a few friends. git.volkor.me It's open for anyone to sign up!.
I'm now running a Mastodon server, just like the other services, it's mosttly for myself and a few friends, but it's open for anyone.
I run a email server for the domains I own - if you'd like an account, please considering funding the server!
