3d design contest makers book email?
I received an email from robot saying I am getting a free book "Congratulations, Instructables.com wants to send you a 3D Design Contest: Makers Book! Congrats on being one of the 50 first people to enter the Chris Anderson 3D Design Contest"
The only contest I have entered is the "I can make it contest" and that was far from being 3D or punctual.
Is this an error because recently I asked for a post card?
