title: PyroCMS form handling
body: <p>I would like to modify the required fields for the registration and the edit-profile forms in PyroCMS. </p>
  
  <p>Unfortunately I cannot find the code which does the form handling (the part where the required fields are passed).</p>
  
  <p>Can anybody point me to it?</p>
  
  <p>Thanks.</p>
