Example of displaying social networking links (Facebook and Twitter) after giving a rating
using the Rate This module in a Miva Merchant store.  This only displays the links if they
gave a rating greater than 3.  If they gave a bad rating you'll want to figure out the 
problem rather than spreading it all over the web.  You'll need to change the product link 
style to match your store.  You'll also need to change the @username in the twitter links to
yours.  The Twitter links have to be attribute encoded so if you have things like 
&Product_Code in your link, it will have to be %26Product_Code.  You'll also need to get 
suitable buttons for your links.  See http://blog.mivamerchant.com/625/free-social-media-icons-for-store/
Spread the word.
