- On desktop browser you can see list of your subscribed communities on the front page of the instance, below the sidebar (you can collapse the sidebar). On mobile you can expand the Subscribed list. You can also click your name in upper right corner and choose profile. Your communities are on the side (desktop) or bottom (mobile).
- You can search for communities either by their name, using the !community@instance syntax (for example, !memmy@lemmy.ml) or by the community’s URL (for example, https://lemmy.ml/c/memmy). That last option usually works, when the other two might fail. If the community is not yet federated with your instance, you can wait a few seconds/moments, and the instance might pop-up in to the search results. Or search again later.
There’s also pornlemmy.com. You don’t need to be logged in to view posts and there’s no anime/hentai or aigen stuff.
