I checked your account and your email address is listed there....can only assume you did provide that when you joined or it would not be there...can't remember is an email address is required to join or not with this latest version of software. Anyway, checked your cp options and you have indicated that you did not want your email displayed to anyone...but you did not indicate in your cp options that you did not want to receive emails from other users. You can do this by clicking on the UserCP button above and go into the Edit Options area and make the change you need to indicate that you do not want to receive emails from other users.
