I mod three niche communities on Reddit. Two are for sites I own and run, and the third is for TTRPG generators. I made the first two private with no intention of making them public again. The third I'm not comfortable making unilateral decisions on, so I'm just un-modding myself for it.
Now I'm considering starting up old-school forums to replace the first two subreddits. It would be a lot of work to manage them over time and I'm not sure that's the best use of my time. However... they would be communities fully under my control.
Decisions, decisions.
