I pre-ordered the product and I did not receive this e-mail either. I forget the exact options relating to e-mail that I selected during the Google Checkout process, but I either chose not to disclose my e-mail address to the seller or I did not opt in for e-mails from the seller. I'm guessing you did the same and that's why we didn't receive the e-mail.
If one of the WakeMate guys read this, it would be good to post this on the blog or main website so people who did not get the e-mail can still get the information directly from WakeMate and fill out the questionnaire.
Yeah I agree, I didn't get this email and I was frantically checking their blog, which looks dead, and their website, which hasn't changed to reflect anything said in the email.
