From the MINDSTORMS website:
"If you own a LEGO® MINDSTORMS® NXT robot, if you live in the area of New Jersey/New York City, USA, and if you are willing (and if your parents say it is ok) for you to help us with some product testing in early October, ask your parents to download and complete the attached form, and send it back to us. Once we receive the signed form from your parents, you may be contacted by a representative from the company, that conduct the focus group for the LEGO Group. If you are chosen, we may end up having you join us to help with some consumer product testing."
