SMAC communities online

What communities still talk about SMAC besides AC2?

r/AlphaCentauri - https://www.reddit.com/r/alphacentauri/ (still active)
Apolyton, the OG - https://apolyton.net/forum/other-games/alpha-centauri (dormant, but so much good stuff in the archives)
CivFanatics board - https://forums.civfanatics.com/forums/alpha-centauri.27/ (there were posts in the last two years, at least)
WePlayCiv board - https://www.weplayciv.com/forums/forum/5-alpha-centauri/ (pretty defunct, but good archival material there including participation by our esteemed host)

Other forums like SpaceBattles and Sufficient Velocity still have some SMAC discussion here and there. Is anyone aware of anywhere else?

Thanks! Glad to see that the community is still keeping track of itself for posterity's sake.

r/4Xgaming has a reasonably strong SMAC showing.  It's the only Reddit sub I hang out on to discuss SMAC, because I do not get along with whoever's moderating r/alphacentauri.  I do all my mod announcements on r/4Xgaming as it's got way more traffic and a pulse.  It's the place where one can reasonably expect to pick up a few new SMAC adherents.
