From a January 13, 2009 email from Michael Chasen to the customers:
Please share any feedback with me directly at a Web site created for just that purpose called Tell Michael Chasen. I will personally read every message I get, so please let me know what you think.
That page in the email is no longer available.
I guess it was moved in the web site redesign for the launch for Learn 9 (Jan 27), then this page lasted at its original location all of 14 days. The new page is Tell the CEO.
A redirect to get those of us who refer to the emails we have received to the right page would be nice.
