For instance, I made an account here in Lemmy.world because it seemed like a nice, well rounded place to start. However, I want stuff from TTRPG.network to show up when I browse my “frontpage,” but all I see is my Lemmy.World communities.
I’m using Liftoff on Android at the moment, but I’m a newb, so I’m clearly not tied to that app.
If you subscribe to the communities, they’ll show up on your front page just like local communities. If you want to browse them, you csn go to lemmy.world/c/community@instance
