title: Django Userena Extending
body: <p>I am trying to implement the concept of "Plans" (free, pro, enterprise, etc.) when a user signs up for my site.</p>
  
  <p>I am beginning <code>Python</code> &amp; <code>Django</code>. I've gotten <code>django-userena</code> installed and working. Now, I am trying to extend the behavior to allow a user to select a "Plan" when signing up for the site.</p>
  
  <p>I believe the plan would be stored in a subclass of <code>UserenaBaseProfile</code>, but not sure... maybe plan choice should not be part of the profile.</p>
  
  <p>What is the best way to implement the concept of "plans" in a <code>Django</code> app using <code>Userena</code> (or not using <code>Userena</code>!).</p>
