  def self.help_text
    %{ 
You can use `amazon:XXXX`-style URLs to refer to items for sale on
[Amazon.com](http://www.amazon.com).  If you provide an Amazon associate
ID in the filter configuration, then each of these URLs will be tagged
with your associate ID and you'll make money if someone buys an item
while using your link.  Example:
         
    <a href="amazon:097669400X">
           
turns into
       
    <a href="http://www.amazon.com/exec/obidos/ASIN/097669400X/scottstuff-20">}
  end
end

Fix amazon affiliate/associate so (a) it's consistent with Amazon's nomenclature and (b) it actually works right
