I am sure you all have been waiting for the Commerce Server 2007 Book that was listed at Amazon and blogged about. If you perform a search now, you will notice that it is no longer available at Amazon. The reason for this is that book will not be published.
I talked with Wade (the author) and he is trying to find another publisher and I may even put a few word in a couple of chapters but that's not solidified yet. As I gather more news I will be sure to let you know.
In the mean time here is my shameful plug :/
So how do I learn Commerce Server?
I have two video tutorials that you can start with and more to come later. Currently I am trying to put together a training session something like the bootcamp sessions I did for Microsoft but more in-depth with lots of samples and labs. The duration of this training will be five days and held in sunny California. Time frame is going to be sometime in June\July. The cost is going to be somewhere around $2,225.00. Of course this will depend on interest and number of participants :).
A rough outline of what is covered:
Installation\Configuration and Deployment
Marketing and Profile System
Data Warehouse and Partner SDK
What you will take back with you:
Lab samples, code and power points of the training session. I will also provide the two training videos as part of this session.
So stay tuned as I get more news on the book and the Training Session here in LA.
