Not that it is not interesting but I would like just a tad more variety on the front page.
Edit btw for those who are wondering the two communities I started are https://lemmy.world/c/newmusic and https://kbin.social/m/musicfeedback/microblog (not sure if I have the links correct for people)
That’s not how any of this works…
Communities (as you put, sublemmy) can’t be individually federated, only instances can be. And needing another account is a sign that you are looking at a post on the wrong instance, not a sign that an instance is not federated. In fact, finding out an instance is not federated can be pretty difficult unless you check the list of instances that are defederated on another instance.
That’s not a universal link, so you ended up on a different instance. A much simpler and easy explanation than what you came up with.
Every community needs to be federated separately, but instances can defederate entire instances. To federate with a community you have to search for it from your instance.
My bad, I’m still learning how this whole thing works, have only been using Lemmy for the last day or two.
I’m starting to figure it out. It’s a little confusing though, as when I subscribe to some communities that aren’t on lemmy.world, they all show as “subscribe pending” for me. But it seems like I am subscribed? Or maybe just seeing it here on lemmy.world but not actually the content on that instance? I’m not really sure. Sorry if I’m adding any confusion here.
Just to answer this part, the pending subscriptions (mostly a problem on lemmy.ml communities but sometimes elsewhere too) seem to be mostly a visual bug. I have a ton showing as pending but posts from them turn up in my feed so I’m clearly subscribed.
