title: Django, register user with first name and last name?
body: <p>I'm using Django-Registration and the form just has 3 fields (Username, Email, Password, and Re-password), but why I can't add last name and first name??</p>
  
  <p>In the Form all is fine but the User Model just accepts 3 arguments:</p>
  
  <pre><code>new_user = User.objects.create_user(username, email, password)
  </code></pre>
  
  <p>but why I can't do that:</p>
  
  <pre><code>new_user = User.objects.create_user(username, email, password, first_name ,last_name)
  </code></pre>
  
  <p>The Django Documentation doesn't say anything about just 3 arguments; all tutorials on the net just use 3 arguments...</p>
  
  <p>Why?? Or how will I make use of first and last name?</p>
