How to add a include-activation to restful-authenticated?

I use restful-authenticated a months ago, but recently I got a spam
problem, so I would like to add a activation function on my site.
so, how to add include-activation to a original restful-authenticated
without activation function?

  1. What versions of Ruby and Rails? – run: script/about in your
    project root.
  2. You’ll need functional email in your project
  3. You’ll also need
    3a) aasm plugin
    3b) rubyist-aasm gem (possibly)
