I recommended the Fediverse to Brennan Kenneth Brown (the creator and developer of fanfiction.lol: https://fanfiction.lol/, which is an alternative to Ao3, but that uses the same OTW software: https://github.com/otwcode/otwarchive/).
And he told me to go ahead and implement, as well as create a pull request.
The issue is: I know almost NOTHING about the technical side of The Fediverse (lol).
fanfiction.lol Codeberg: https://codeberg.org/brennanbrown/fanfiction.lol
So ehm... What is your question?
