Dor, I've been answering this question in 2-4 replies a WEEK for the last 4 or more months on U.Hall & Players Corner.
The only way, after so many times, anyone could be missing the posts & replies about this, is not reading past a certain number of pages (typically, by the time a user logs in for the afternoon or evening, US time, the posts are on the 2nd to 4th page (at 25 posts, plus stickies, per page). Most of the time, I'm ON at 5-6 AM answering these, on Tuesday Mornings)
It's one of the reasons I start reading U.Hall on the page with the oldest unread posts, and work back to page 1.
