Funny, this section doesn't mention Mojave or Catalina yet. And now Big Sur is coming. ???
I've questioned that twice.
The first time, cyn's response was that "forum descriptions [had] fallen off [her] radar;" the second time hasn't elicited any response.
Seems to me that new visitors may see that the forum descriptions are out of date and that the Lounge has got half again as many posts as the Mac OS X System Forum (which is deceptive in and of itself), decide that we've given up the ghost, and leave without looking.
Got me beat. ¯\_(ツ)_/¯
