First off, sorry if this is in the wrong spot, I couldn't find an area for problems with the forum.

For the past week or two (I can't remember exactly when it started, as at first I thought it was a random fluke) the forum has been randomly logging me out, despite the fact that I click "remember me" every time I log in. Previously I was able to not visit the forum for a week or two and still be logged in when I came back. Now I can be on just fine and a few minutes later I realized it logged me out at some point.

I'm using Internet Explorer 8 and haven't been having problems with the other forum I'm on. Any ideas?
