@teknevra@lemmy.world The work done by the developers, and @julian@activitypub.space in particular, has transformed NodeBB from a forum platform to a federated platform with categories that can be used by users of other NodeBB servers, as well as Lemmy and Mastodon users.
I recommend checking out some public NodeBB servers (my server, however, isn't suitable for you, as it's reserved for an Italian audience).
