Thanks for joining the eviltoast.org lemmy instance!
We're still figuring out how all of this works, but lemmy itself should be relatively stable for now. I plan on also launching a new Matrix server in the next week or so as well, using the same domain.
If you're new to lemmy, I recommend checking out this post from lemmy.world to get started:

For mobile clients, Jerboa and Liftoff have both been good so far. Jerboa is the official client, but Liftoff felt a little more friendly. Mllem seems to be a decent ios client, but I haven't not used it much yet.
There isn't really any content locally on eviltoast.org right now, so I'd recommend setting your default view to either All or Subscribed so that you actually see something in your feed. That said, you're more than welcome to create communities and post locally as well as to other lemmy instances from here.
