Hello this is my first comment on Lemmy, so consider me an expert.
The idea of ‘federated’ websites is that you can use your login from one server to interact with another server. An analogy is email: you can have a gmail account that can send a message to a yahoo account via shared and open source protocols (e.g. SMTP).
One question I do have though; if I create my account on Lemmy.world and then for whatever reason that instance disappears; does my account disappear or is it recoverable on another instance?
