I'll try to look into this further, but I'll need some info first. If you're having a problem logging in, staying logged in, or even NOT having a problem at all, please answer these questions:

1) Which browser are you using?
2) Have you tried a different browser, and how did that work?
3) Have you tried "expiring" your Cookies via the BB?
4) How often does this happen?
5) Has it happened on other websites?

As for MY experience, now and then I find myself having to log in, when in the past I was ALWAYS logged in. Chrome is my main browser, but haven't tried another browser long enough to tell if it'd happen there. It seemed to be okay for about a week after "expiring" my Cookies via My Stuff here on the BB, but I'm not sure if it's the BB itself, because the same thing happened to me at ESPN.com

That, of course, makes it difficult to track down the problem, but hopefully if a bunch of people chime in with their details, I might be able to narrow the issue down....
