What's with the paranoia?
Is it an insane, convoluted plan to thwart Bill Gates from knowing your location, but leaving the field "blank"? If Bill wanders down to FL (USA), he better pack a lunch, and bring a truck to carry-off my Commodore hardware. And that's after I unload a full magazine.
Examples of why to stop the paranoia.
(1) Selling - monitors are heavy. With locations, you determine average shipping weight before hand.
(2) Helping others - sometimes it's easier to help someone else via a phone call. Really don't mind it! But, senseless to offer a PM to help via phone, only to be told, hey guy, I am in the UK.
