This site is currently struggling to handle the amount of new users. I have already upgraded the server, but it will go down regardless if half of Reddit tries to join.
However Lemmy is federated software, meaning you can interact seamlessly with communities on other instances like beehaw.org or lemmy.one. The documentation explains in more detail how this works. Use the instance list to find one where you can register. Then use the Community Browser to find interesting communities. Paste the community url into the search field to follow it.
You can help other Reddit refugees by inviting them to the same Lemmy instance where you joined. This way we can spread the load across many different servers. And users with similar interests will end up together on the same instances. Others on the same instance can also automatically see posts from all the communities that you follow.
Edit: If you moderate a large subreddit, do not link your users directly to lemmy.ml in your announcements. That way the server will only go down sooner.
I found it rather easy to get signed up, just had to wait for the admin to actually approve the application. Otherwise it was pretty easy.
However, I do see a HUGE benefit to “load balancing” as you are mentioning. Where you sign up for a master server and then replicated to the others that are more applicable. I’m surprised this isn’t already a process as this is very common in gaming and proxied sites.
Yeah the registration itself was easy like any other site, I was talking more about grasping and understanding the concept of instances and how they interact.
And as someone said in another comment, the see all posts options should be the default in your home and community search or you feel like in a dessert island when you are new to all of this.
