I would ask EVERYONE who pre-ordered, whether your address changed or not, please go to 7800xm.com and fill out the pre-order form, I want everyones info please. Make sure you are including your address if it is not on the attachments you are putting into the form. thanks.
Just curious, have you tried emailing everyone who pre-ordered to ask them to go to 7800xm.com to fill out the form? I'm sure you'll get some bounces, but at least this would reach hopefully a large percentage of those who placed orders.
