I'm an admin of tilde.fun. I'm currently migrating everything to a new server, so our SSH registration script is nonfunctional.
If you want to have an account, write an email to my username @tilde.fun. Include your SSH pubkey and your desired username and password. It'd be nice if you also included your name, but I don't need to know it.
have a nice day :)
I have an RSA pubkey and an EdDSA pubkey. Please use the latter if your mail client supports it.
