Glad to hear it worked out! I forgot exactly what I typed when I was trying to federate that community I was looking for. So a couple of follow-up questions, if you don't mind lol. Still trying to wrap my head around this stuff, myself.
When you say that "legostorage@lemmy.world" didn't work for you, did you mean you had to type in "@legostorage@lemmy.world" instead (with the @ sign at the start)?
