Do you share an email address with another person registered on this site? If you do, you should understand that the "Request New Password" functionality uses the email address you provide to look up the user account that is to receive the new password. When there is more than one user account associated with one email address, the password reset function will change the password on ALL OF THEM. That might be frustrating for the others using the shared email address if they are unaware that a new password has been requested, and they miss the email informing them of the change. Please be sure to coordinate a password reset with the person sharing your email address.
