While I’m saving most of my feature requests for after I’m done bug hunting, I thought that extending the same level of searchability to Mbin and Piefed communities would increase the number of communities users have easy access to, along with making it more likely that those communities get new Lemmy users to join.

Of the two, I’d guess that Mbin would be the easier one to implement currently, given that Lemmy Explorer on lemmyverse.net indexes them in a similar manner to Lemmy communities.

If the functionality were implemented, ideally the Mbin and Piefed communities would be searchable via the current Lemmy Explorer tool, perhaps with a filter option to toggle the listing of communities from any of the three services on or off.
