I'm brand new and I have spent ~~almost a week ~~ a few days trying to log on for a second time (first time worked great, always timed out after that). But I'm here now!

One thing that has been frustrating is that 90% of the time I've seen someone say that it's confusing, people just say IT'S SO EASY, TRY LEARNING and then the learning materials describe the concept of the fediverse and Lemmy but not how to use it.

I still don't really understand. I've used a hundred different forums and forum-adjacent type services, and Lemmy seems to be similar enough to Reddit, except that each server is it's own reddit, but if anyone on the server is connected to another server, it'll pull in communities followed by anyone on the server?

Again, I don't really get it. I'm trying, but it's a bit confusing. I get that it's decentralized and all the servers are unique and it's one login, but I don't get how the communities fit together between servers, if they do at all. Would this mean that we can have duplicate communities on different servers?
