Any chance Adobe can add an option to stay logged in indefinitely (or at least extend the expiration period)? Many forum/social sites have an option like this or do it by default (e.g., Gmail). Call me (really, really, really) lazy, but having to log back in periodically means I sometimes don't answer forum questions if it means having to log in again. If I'm on my personal machine, I don't see the benefit of being logged out for a site like Adobe forums (my bank's site, sure--but not here).
This is probably not as easy as I make it sound due to server-side session state, but it's something to think about.
Always being logged out drives me nuts. It may not be so mad if they had other avenues of participating, but I don't believe any of them work.
Having to log in everyday is a real hurdle and has definitely made me stay away from hitting reply button; or actually finding the damn 'reply' button when I have been logged out after just 24 hours!
