What worldbuilding communities are you a part of?

The lion's share of my work is on the CBB. I was active on /r/worldbuilding before quitting Reddit in 2023. Prior to that I was a lone conlanger/conworlder since the late 90s and only recently thought to seek out others like myself.

Besides this one, the Discord server of a more military-focused Worldbuilding community that spun off a Subreddit a while back, and a couple fiction writing communities which guess kinda count?

Fediverse-wise, this one. Are there any others?

The other ones I'm in are more fandom-topical, so for exmaple a few specific communities on Pokémon worldbuilding. Nothing "generic".

i post most things to my tumblr page
