Net Sentiments Offering $10 Amazon Gift Certificates for New Members

Recently, my friend signed up for surveys on Netsentiments.com. She told me that they offered her a $10 Amazon gift certificates just for signing up and filling out a registration form at http://www.netsentiments.com/registration.htm . Anyhow, she did get her amazon.com gift certificate by email but it looks like netsentiments.com has put registrations on hold because of the overwhelming demand. I'm told that Netsentiments will be re-opening the registration process soon and they might give out a few more Amazon gift certificates to lucky participants in the near future.
