Good morning team! Still trying to figure out lemmy and kbin now that my app of choice is dead..
I'm a little confused, I signed up on a different server/instance, I can't login on the lemmy.nz instance but I can still post from the other server to it, is that right??
That's right. The instance you signed up to is basically your home base but you can still interact with communities on other instances and add them to your subscription list.
Each instance will have it's own set of rules and moderation process (Beehaw is moderated and limits new users, lemmy.ml has a political angle etc) so it can make a difference. I signed up to lemmy.nz because I was already on mastodon.nz and am chipping in for server costs, and because I wanted a properly 'local' local feed. Plus the community here is pretty awesome.
It matters in a few ways. Instances can defederate from each other, so you have to keep that on mind when choosing where to sign up.
Also when posting something, you have to think about the rules of the server you're posting on and your home server. Even if the server you're posting on allows it, your home server may not like you posting it.
Yes, you use the instance you signed up on to interact with all the content. Lemmy is new so some things are a bit janky but if you have trouble feel free to post to !support@lemmy.nz
