With an account on panthermodern.net you'll be able to follow people on any Mastodon server and beyond.

You'll have to ask me or other users for now, I'm not ready to handle too many users yet. Still getting the usage stuff down. I'll add, that if you get in, you get in, and you can invite others, in other words, invite only atm. If you have an invite, good on you... But if not you can probably reach out to me at seven@panthermodern.net and sooner or later I will get to you, and maybe just grant access... It's not super likely, you kinda need to win me over, I'm a bit of a asshat...
