NRSK have made an unofficial info page for new and old users alike. If you are new, or want to introduce someone to Lemmy, maybe this can be a useful tool? Perhaps you’re an old-timer who’ll find some interesting new communities to subscribe to? If you have any feedback or want to add to the list, drop a comment or post in https://nrsk.no/c/welcome. Right now the list is manually curated, but long term ideas such as direct user submissions is being explored.
