The number of times a day is not the issue Gil. I read the forum at least 3 times a day, but You have said earlier that you never sign out. The problem we have is that sometimes we want / need to take a quick look or look up something specific, but not read everything "new" and we may not be on our normal machine. Say someone takes a quick look for something at work, but does not have time to read all the new posts. Now we have to log out to get back to work or to leave the office and then log back in at home. Once you log out the new posts since last visit is reset and those "new messages" that did not get read, are no longer considered "new" That is the reason for requesting an unread posts and not just new posts since last visit.
