The one I've put the most into lately, lets see. Note I do not own it, I just happen to be the most pro/active admin in its late life.

Caveats: A lot is hidden, a lot is buried away. Plentiful spam, calling over a full third of all members as well as a massive chunk of posts/threads spam is not exaggerating. Certainly spam props up active members, and many more are lurkers/occasional visitors for the old content. Online at a given time there are a dozen, dozen and a half people, dropping down to a couple and capping in the 20s (usually with spam help). Many of those lurk or post very intermittently, there's probably a solid dozen who count as active in a forum engagement sense.
The highest number online was a few thousand in 2015 up to a few years ago, again probable guests/spam as the site's peak activity tapered off in the early teens. I showed up 2017 and had a bumpy ride getting to actually work on it, and being mature enough to do it any good.
Daily posts range from a handful at worst to nearing 50 on a particularly good day, and typically somewhere in between through both topical game/mod related content and more frivolous content.
