To answer HulaMoon's question, I did receive the standard auto-reply, and then a very short "Thank you. We will be visiting your blog and will be interested in reading comments..." message. Enough of a response to fan my tired spirits. :) I have to think they have received quite a number of emails regarding CPSIA, so perhaps, just maybe, a few more emails will do the trick.
Thanks to all of you for your comments. What a great bunch!
