Gitea Account Setup
To create a Gitea account on aipt.group, select "Register" in the upper-right of any Gitea page on https://aipt.group
To create a Gitea account on aipt.group, first join the Matrix server and then ask an existing Gitea admin on the aipt.group Matrix server to create an account for you.
This account is not (yet?) tied to either your Matrix account or your shell account (optional).
Definitely use a throwaway password. This is a self-administered server, and may not be all that secure just yet.
You will need to coordinate with an existing Gitea admin once you've created your account to get access to various other things.
Additional Notes
Not as feature-rich or polished as GitHub.
No simultaneous editing like with Google Docs.
