This happened a few times already. So, I decide to post the issue here and see if I did something wrong or what I encountered was normal...... I signed in a moment ago and clicked at Alerts at top right corner next to my name, I got a box saying I must sign in first. But I was already signed in. see screenshot: And then, I decided to post my question here, and once again I was told to sign in. Do I have to sign in each time I login to a different forum, such as from Win 7 Support to Win 8 Support ? It is inconvenient, not to mention irritating.
