If you are having any ‘user account’ issues with the website, I recommend you check out this FAQ PDF (click).
Sometimes people think they are logged in when they are not, because the website (as a security feature) automatically logs people out if they are inactive.
The problem is that most browsers don’t update automatically.
Most browsers pull content from pages ‘cashed’ (stored) in the computer, to speed up internet surfing, and those cashed pages don’t show the actual logged out status so it LOOKS like you are still logged in, when you are logged out.
If having troubles accessing ‘user-only’ features of the website, just log out and log back in and it should clear up.
