Authors’ Acknowledgments
I want to thank the people at Wiley for their hard work and continued support. A special thank you to acquisitions editor, Katie Feltman, for asking Ed and me to do the third edition of this book and for her patience as I worked through the chapters of this book. I also want to thank project editor Pat O’Brien for his patience and hard work keeping Ed and me on track! Much appreciation goes to copy editor John Edwards for an outstanding job on the editing of the chapters. I also want to thank Dan Lachance for his feedback as the technical editor and a job well done!
Over the years I have developed friendships through my work, and one of my favorite people to work with is the coauthor of this book — Ed Tetz. I want to thank him for the long hours he has dedicated to this book and for once again doing an amazing job! I also want to thank the folks at Tim Horton’s for not kicking me out when I occupy a table for hours at a time and for keeping the coffee always fresh!
A special thank you goes to my four children, Sara, Brendon, Ashlyn, and Rebecca, for giving me the time to sit down and participate in kids play with them — it makes me realize what is important in life. A needed thank you goes to my wife, Tanya, for all her support — you are amazing! Thank you for all that you do!

I would like to thank Katie Feltman, our acquisitions editor, for inviting Glen and me to take on this project, and to both Katie and Pat O’Brien, our project editor, for keeping this book on track, which I am sure was an effort for them, and thanks for that. I cannot forget John Edwards and Heidi Unger, our copy editors, for their work of ensuring that what I wrote made sense, and in many cases, making my words sound better than when I originally wrote them. And a special thanks to Dan Lachance, who I first worked with as a technical trainer; Dan did a great job as technical editor on this title, making sure that everything was accurate.
In addition to them, I would like to thank the rest of the staff at John Wiley & Sons, Inc., who worked behind the scenes taking care of many of the details that are required to get this book into print, and I am sure that due to their hard work, this will be a successful book.
