Alongside Discord, we have the /r/freebsd subreddit; a Matrix instance (not yet listed); The FreeBSD Foundation on Mastodon (not yet listed); and so on.

The last update to the Community page was by me. In an ideal world: I'd now add what's missing. In reality: I chose to resign (my doc commit bit was taken in for safekeeping).

Side note: when I last checked, servers for The FreeBSD Forums were not (officially) hosted by The FreeBSD Project.

HTH
