I am having the same issue as coius. Was browsing around here then spent some time talking with BoIIe about that 4400 on the IRC channel. Then I come back here and reload a 68kMLA page and I am logged out. I have not noticed this on other forums and it has happened here a couple times since midnight or so.(7:32 AM now)

In fact I had to log in to post this. -_-
