Problems logging in? - cookies MUST be enabled in your internet browser for you to be able to login! - a typical sign of disabled cookies is if you after logging in are presented with an empty profile creation page (see help section then).

Auto login stores a cookie on your computer which the site later can recognize and identify you by.
It is NOT recommendable to use the feature on public or shared computers as it enables other users of the computer access to your profile if they access the site - if you by accident enables auto login and want to disable the feature it can be done from your 'My profile' page (uncheck the checkbox for auto login and update your profile)
