The “showing more communities” part is called federating. basically, an instance (@lemmy.world in ur case) has a bunch of communities. now the owner of that instance can “federate” with another instance, so that you can additionally view their communities as well.
I’m a complete newb with Lemmy as well, but as far as I know, lemmy.world for example only defederated some extremist instances (and threads if I’m not mistaken?)
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]
