title: Email confirmation rubyonrails
body: <p>I'm trying to create a website where the user signs up with his user name, password and email address. Then he should be sent a confirmation email which generates a link he will have to click on to make his account approved.</p>
  
  <p>How would I do that, anyone who has a tutorial that's very simple and easy?
  I'm just looking for the most simple and easiest email confirmation code.</p>
  
  <p>Thanks,
  Michael.</p>
