my Ipad does the same, only thing is that it actually HASN'T logged off like it would seem on the main page; as soon as I click on anything (typically "forum", any thread or "unread content") it shows me as logged in. No idea what's going on, but it's probably just another one of the joys of Apple ownership.
The weirdest thing that has happened a couple of times is that instead of showing me as logged out initially, it appears as if I'm actually logged in as another user (different user names both times). Again it gets resolved by moving to another section of the page.
@Sinclair89 I love the pinup - and the fact that it is modeled after your wife makes it even more special.
My son and his wife went the more renaissance direction for their wedding. This was taken just before the wedding ceremony.
