I’ve got an account on lemmy.world. “Lemmy” know if I have this right? I can search communities on other nodes but if I want to create a post in a remote community I’ve got to create an account on THAT node? Or am I missing something? Also, what is the android app everyone is liking? Jerboa is usabl, but lacking.
No, you just need to go to that community while logged in with your lemmyworld account. Usually the url will become like this: http:// lemmy[dot]world/c/[email protected], and once you open that, you can post normally.
Yes, the point is to be able to participate in communities from all sorts of instances using your one account.
In fact, some people don’t even have a Lemmy account, they subscribe to communities from mastodon or pleroma. It’s not even the same kind of software but it’s compatible.
