This issue is very strange. If I follow a link to experts-exchange from my email, it appears as though I'm not logged-in. When I go directly to experts-exchange (not by following a link from email), it looks normal.
In the attached screenshot, the page on the right is the one I'd followed from email (center bottom); the one on the left is a new window I'd opened with the entire URL pasted in from the other. I reloaded both pages, and they both continue to behave the same (one's logged-in, one isn't).
