I have been having this issue on the offical forum since the Beta before last. During that time I asked a Question in the "Ask a question" forum but I never got to click to accept an answer during that weekend. Still now, on the LIVE forum, every single page I go to I get the flag pop up below saying "You've asked questions that now have answers". In the past if you hit the flag it sends you to the message, you hit accept and its gone. But for the last few weeks it send me to a blank page, saying I have no discussions, even when I try and take the long way around to the page I apparently haven't posted anything. Even though it shows the numbers of the things I have. So seemingly there is no way to clear it.
So far during the choice of the last three weeks the Customer Service has been next to useless, just sending me form letters back, one or two obviously not having read the problem.
