First and foremost, we would like to thank our parents, Walter and Beryl Fenlon and Mike and Marlene Hawley, for without their love and support, we never would have made it through.
Thanks must also go to the team at O’Reilly, first and foremost Brian Sawyer, for all the hard work that he has put into this book. Andy Pope and Dennis Wallentin must be thanked also for the hacks they contributed, and we have to mention all the visitors to our web site and forum, who helped us to identify some of the most common issues that people face.
We would also like to say a special thanks to all moderators and Oz MVPs on our free Q/A forum who share their time and knowledge in such an unselfish way. Finally, we must thank Aleisha and Kate, as always, our inspiration. Their understanding and extra efforts to be good while the book was in progress will be remembered!!
