+Note, The 'known_user_role_details' cookie is created by this module when 
+a user logs in, and it will persist for a month, storing the user's id and 
+firstname. With Caching turned on in Drupal, there can be problems with the 
+names being displayed in the login block, and the problem is fixed by using 
+a script to apply the last login name to the home page. For the script in 
+this module to work, certain elements need to be applied to the theme 
+template.php file. Namely '<strong class="welcome">' and '<strong class="notyou">'.
+
+For example...
