The way Lemmy works right now is you search a community in your instance for it to then get shown, so you need to first discover that community from elsewhere. With that in mind, what are some growing communities that you discovered that could get some more love?
I think it works like this: each account belongs to an instance which is your home instance. You can go to other instances to interact with their communities, but your profile (where your history is) is on your home instance. The only difference I’ve notice is that, posting on your home instance then your post is just username, but on away instances it’s username@homeinstance. Otherwise it seems to work the exact same as interacting with communities on your home instance. But I’ve only just signed up so I am making guessing!
