 * Thank you! The plugin is great and works with WordPress 4.
 * If anyone can assist with my challenge here?
 * I am looking for an added functionality and not sure if its possible. I want 
   a user to register using email address, some other information and an ID number.
   The ID number can be added under the custom field, but what I want is for a user
   not to be able to register if his ID number has been used already?
 * Is this possible for the plugin to check custom fields and not allow registration
   if a field exists, or do you think there is a workaround to this?
