title: Rails 3 - Oberserver - Not able to user the Devise @current_user
body: <p>Im building a Rails 3 app, and have an Observer...</p>
  
  <p>in the observer I need to user the current_user var that DEVISE allows me to user across my views...</p>
  
  <p>How can you use the current_user.name or current_user.id in the Observer?</p>
