How to send email to user after registration(Devise gem)
===

<p>I have already made Recoverable module working, so all my setting for mailing are set.
<p>I need to add mettod in my mailer class:

     def congrats(user, password)
      @user = user
       mail(:to => user.email,
         :subject => 'Congrats message')
      end

I will use http://railscasts.com/episodes/206-action-mailer-in-rails-3 railscast for doing this
<p><b>BUT where I should call congrats method ? In after_sign_up_path_for  or not ? What would be the best practice ?</b>
