title: django-registration with paypal integration
body: <p>I'm trying to figure out how to integrate django-registration with django-paypal.  Being a Django n00b, I'm trying to figure out how to implement a flow like this:</p>
  
  <ol>
  <li>User signs up using django-registation with 'active' flag set to 0</li>
  <li>After registering, send user to PayPal for a subscription</li>
  <li>When they come back from PayPal successfully, I want to set 'active' to 1</li>
  </ol>
  
  <p>I've been looking at the django-registration documentation and don't quite understand how to use different backends or implement a flow the way I want.</p>
  
  <p>Any tips on how to accomplish this would be greatly appreciated.  django-paypal won't be a problem for me as I've done PayPal integration before (in PHP for a self-published book about CakePHP).</p>
