Sorry but you aren't registered. Go to this link http://www.diaperdecisions.com/pages/gcdhreg.php to register.
How do u register? I went to the FAQ and looked that part up and all it says is that you can register between Apr. 16 and May 31. I filled out to receive their newsletter but under the FAQ it talks about changing phone number and address info. I didn't have to fill any of that out. I've found 3 of the little dipes and I used the same e-mail that I used when I signed up for the newsletter. Hope it works
