Therefore I assume that it requires an admin approval to bundle these “Topics” together, and it definitely doesn’t strike me as something that an individual user could put together.

That’s why I’m saying it’s not personal multi communities, which is something people are definitely looking forward (most upvoted Lemmy GitHub issue)

I remember discussing personal multicommunities with @rimu@piefed.social a while ago, at the time it was not a priority for Piefed, maybe they’ll revisit in the future.
