Didn’t actually realise that the #StarTrek subreddits of /r/StarTrek & /r/DaystromInstitute had a #Lemmy community @ https://lemmy.world/c/startrek@startrek.website @startrek.
Given Trek fandom are often the first colonizers of online spaces in internet history (eg newsgroups) losing major Star Trek communities is big L for Reddit.
EDIT: Not permamently locked subreddits, got that wrong I think!
Can’t wait till they bring up a ShittyDaystrom. I’ve got a post brewing about how the Federation wouldn’t exist without disgusting Ferengi sex programs. It’s way too long and snooty for Risa, and far too ridiculous for the actual Daystrom. :(
