There should be a universal community search engine for the Fediverse where you type in a community description or keyword and the service returns a list of all similar communities across all of the instances. It should be called Feddle (the Fediverse Google.)
You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: [email protected]
A community to talk about the Fediverse and all it’s related services using ActivityPub (Mastodon, Lemmy, KBin, etc).
If you wanted to get help with moderating your own community then head over to [email protected]!
Rules
Posts must be on topic.
Be respectful of others.
Cite the sources used for graphs and other statistics.
That sounds like a great thing for you to build, yes.
I don’t know how.
