Thank you so much for the education. It was really great and I appreciated your candor regarding other data centers. I also felt that you did a great job considering that you were sick. I felt that the book was great because it was written in terms that most people can understand. You covered the points that most people struggle with, i.e. cooling, generator power and *n*. We felt that we got a lot out of the course and there isn’t a negative comment I have…wish I could pick it apart for you…but I can’t. It was really great.
