 * Hi there, maybe im trying to do somthing that no-one has thought of yet or maybe
   im just rubbish at researching on the internet.
 * I have a wordpress blog and I have restricted the login to only allow people 
   to join via a facebook connect button (Plugin: Facebook AWD)
 * I am also trying to create an afilliate page for people to refer their friends
   using Affiliate Plus Plugin
 * I cant seem to work out how to insert the affiliate plus hooks to work when someone
   registers with the facebook connect plugin
 * Below is the facebook login process file:
 *     ```
       <?php
       /*
       *
       * login AWD FCBK
       * (C) 2011 AH WEB DEV
       * Hermann.alexandre@ahwebdev.fr
       */

       */
