 * I added a checkbox field using a pre-existing meta field (from the User Meta 
   plugin which I am hoping to replace with yours) and I got these PHP errors afterwards:
 * Warning: explode() expects parameter 2 to be string, array given in /home/mysite.
   org/wp-content/plugins/users-ultra/xooclasses/xoo.userultra.user.php on line 
   1529
 * Warning: in_array() expects parameter 2 to be array, null given in /home/mysite.
