title: Django admin - Email username and password on user creation
body: <p>I'm using django-1.4.3 and the superuser can create users and assign password to them. Here I'm using <a href="https://github.com/dabapps/django-email-as-username" rel="nofollow noreferrer">django-email-as-username</a> to enable users to login with their email as username. When the superuser adds a new user, the newly added user should be notified through email with his username and password.</p>
  
  <p>I'm able to send email after user creation using <a href="https://stackoverflow.com/q/6593348/1095090">post_save signal</a>. But I couldn't get the password as it will be encrypted and stored. I want to email the user, the raw password. How can I achieve this?</p>
