General User Experience


Let users know if a page is programmed to 'time out', and warn users before time expires so they can request additional time.


Some pages are designed to 'time out' automatically (usually because of security reasons). Pages that require users to use them within a fixed amount of time can present particular challenges to users who read or make entries slowly.
