# The Tagging join model. This model is automatically generated and added to your app if you run the tagging generator included with has_many_polymorphs.

  # If you also need to use <tt>acts_as_list</tt>, you will have to manage the tagging positions manually by creating decorated join records when you associate Tags with taggables.
  # acts_as_list :scope => :taggable
    
  # This callback makes sure that an orphaned <tt>Tag</tt> is deleted if it no longer tags anything.
