I felt it would be more secure for a user to be logged out when they close their browser. This can be done by editing your settings.php file. The default location for this is /sites/ericlondon.com/settings.php. Located this line of code:
<?php
ini_set('session.cookie_lifetime', 2000000);
?>And change it to:
<?php
ini_set('session.cookie_lifetime', 0);
?>This is the default PHP setting.
