Roger, I really suggest you take down the product and delete your post. Really. WotC has a vested interest in ensuring that people follow the license to the letter all the time, but especially at the beginning, and especially because it's a trademark issue.
Saying more so that you know you're in violation makes such response that much more imperative that they punish you.
For your business, and any chance to use the GSL in the future, comply with the license in all ways and in all times. What you've publicly admitted to doing is trademark infringement at the least.
I'm glad you enjoy our products and hope you respect my opinion enough to pull the product down and comply with the license because it is in your own benefit.
