@Region Philbis,
That rings a bell. A growing number of months ago, maybe four, I suddenly couldn't see a lot of posts, as if many a2kers went on vacation all at once. On the new posts page, there would be hours between posts by anybody, in times that usually were busier. I could not see some threads I had started not long before, and would finally find them in My Topics. Sometimes I found threads in that list to the right bottom side of the New Posts page, that I hadn't found on New Posts. I whined to the mods, trying to explain myself/travails. Then one day it was all better. (Thanks, mods, or the hamster gods)
