Thank you very much for the appreciation, as well as for your own work!
I decided to bite the bullet and make a non-disposable email address so that I could create my own account on Codeberg, though I don't intend to actually use the email address. I will need a lot of time to learn how to use Codeberg, as I know basically nothing about git.
When I am ready to start using my Codeberg account, I will make a post here on the fediverse.
