Here’s what I’ve gleamed. Say you make a magazine for toys. It is now addressed as [email protected], you associate the word toys as the badge for it. You’ll see things posted in microthreads that have that badge under that magazine. However that magazine is separate. Every so often Lemmy will download changes from federated servers like kbin. It will then add your [email protected] and users will see it when they search for toy based Lemmy channels (not sure what it’s called). But from that point on, Lemmy will refresh with changes you’ve made and it’ll show up over there. Thats how you browse Lemmy stuff here.
