You probably don't want your email address so public Steve, everyone but customer service will see it. Login into your account and go behind the scenes (the option is a drop down menu under your name) , scroll down to statistics and chose comments. At the top of the page is a question about receiving emails - chose no and submit change.
Ok I was wrong - those are the instructions for turning off comment emails. Behind the scenes scroll down to community, you will see an update button, chose that :-) Remember to "submit" your changes.
