1. My month of being logged in ran out while I was in the middle of composing a post, and when I hit "Submit" I was redirected to a login page that didn't present me with a "Remember me..." box, so I had to log out and back in to get to a fully functional screen (and a complete set of cookies).

2. After dealing with the first login screen I hit "Submit" again and was informed that my post had already been submitted and the button was disabled, but when I logged in the second time it was nowhere to be found. (Good thing I had the presence to copy it.)
