title: Easy-to-use django captcha or registration app with captcha?
body: <p>I want to implement user registration using captcha in Django.
  The workflow of <a href="http://bitbucket.org/ubernostrum/django-registration/wiki/Home" rel="noreferrer">django-registration</a> app is a great, but it doesn't have captcha.</p>
  
  <p>What captcha would you recommend to use with it?
  Are there some other variants of registration+captcha or useful links on the topic? </p>
  
  <p>This should work with Django-1.1 and don't be too hard to install.</p>
