 * wow – I just read this too. Hilarious. You too are also a paying member of our
   BETTER hosting society. Notice – I fixed “wishing”s problem and made him more
   compliant for Google. He is now ranking for his local keywords where he was not
   before.
 * I will also mark this topic as resolved and send you a hilarious email afterwards,
   Mr. Baker.
