I use Bookstack for a family wiki. I probably would not have gone with it if it had not be hosted on Github as the visible activity on Github makes it clear that it's a project with momentum (18k stars, lot's of activity) etc.
I can't help but feel that moving will make the project less successful than otherwise...
Looking at those who have starred the new Codeberg repo, at least 15 people are new today, and thus form part of a bigger audience on Codeberg.
Since they are keeping the github as essentially a mirror, doesn't this obviate those concerns?
-edit- although also:
>although eventually we will only create releases on Codeberg so it’s advised to watch/subscribe to them there instead:
I guess someone _else_ could choose to fork and keep up-to-date.
