Say I am looking for fellows who use FreeDOS. I open the “Comunities” tab(?) at the top of the page, right next to “Lemmy.one” and search - But these are only the communities that Lemmy.one knows about, right?
Thanks, everyone - I am gonna call this one solved.
That approach is even more limited - it’s only communities hosted on lemmy.one.
This is the site you want to use to search across (most of) the fediverse:
https://lemmyverse.net/communities
The best I could do for your (very obscure) request is !freedos@lemmy.ml
