   AutoBlink - Puts Google's Autolink on the Blink :)

   -
   AutoBlink will disable Googe's Autolink feature,
   keeping web site visitors on your web site instead
   of letting them leave through Google Created Links.
   
   Alternatively, if you have an Amazon.com Affiliate
   Id, enter it below and AutoBlink will rewrite the
   Google created links to include YOUR Amazon Affiliate
   Id instead of Google's, so even if people then leave
   your web site, it'll be through Your Affiliate Id
   and you'll earn commissions from their shopping.

   Simply leave the "amazonaffiliate" value blank if you
   want AutoBlink to simply disable the Google Autolinks.
