By the way...for those interested...it will conflict with AdSense if you don't specify in your AdSense account to let
www.google.com/coop access to the AdSense account.
Email I received from Google:
"You are receiving this email because you recently requested access to use
AdSense through
www.google.com/coop. In order to use AdSense features through
www.google.com/coop, you'll need to give the site access to the ad
code and performance information in your AdSense account."
