Yeah, they know more than you think. I belong to a site where I would guess the average age is 65+. It's a Vbullitin site like this but the later version and lots of advertising for non paying members. I think the most I've measured is 64 cookies while just signing in as a paid life member. Anyway with all that shlt going on it hiccoughs sometimes, and these guys get flummoxed. The standard advice is, ask your grandchild to fix it.
