Though I have personally seen a picture of Feuerstein's email that was posted to the Internet over the weekend, I am having difficulty finding it at the moment.
I will keep looking. In the meantime, here is a post from the YMB claiming to show word for word what Feuerstein wrote in his email to Olive / Holly Kennedy.
I have also seen where people have written emails to Adam's boss at STAT, Rick Berke, Cofounder and Executive Editor ( email@example.com ). And by the way, here is Feuerstein's email addy: firstname.lastname@example.org
