I haven't noticed being logged in as another user for a few days now.
The quirk I'm experiencing now on a couple different machines is when I go to post a comment, I get an Error Message: your session has expired
Then I look up and the screeen still says "Welcome, Pinski"
Doesn't happen every time but almost every time, and the post usually goes through after a couple runs at the Post buttom. Only lost a couple full messages.
