So r/startrek opened their subreddit back up.
https://www.reddit.com/r/startrek/comments/14aifzm/rstartrek_reddit_and_the_future/
But they’re still committed to their #Lemmy instance too. Interesting experiment, running dual communities on both sides.
If the mods from the subreddit create/run the community or magazine in the Fediverse it is definitely corresponding especially if said mods spread the word on Reddit (which is not against the rules as far as I know)
