I checked your profile. None of your information, not even your email address is visible to active users, only staff can see it. For people in the future who want to ensure that information is secure leave the 'allow users to email me' box in the Profile -> Accounts Setting page.
Other personal information is located on the Profile -> Forum Profile page. Just empty any field that you filled out and save it.
As I stated above only staff can see your email address. I've been here since August 2005 and have received maybe 3 or 4 emails from this site that were basically News letters. If the prospect of this bothers you then change your email address to something like noemail@noemail.com
Good life to you, wherever you go.
