I would like to thank everyone who helped me with this book (and the companion first edition). The staff at Packt (including Sneha, Swapna, Kartikey, Lata, and Douglas) has been especially patient with me as I juggled the demands of work, writing, and a new baby. There are countless others at Packt that I don't work with directly but that I also know have contributed to this book — thank you all.

Next, I'd like to give a big thank-you to my technical reviewers: Sarah Peterson and Bob Sutton. It is thanks to their meticulous and honest feedback that the book is as good as it is. Any errors, of course, remain completely and utterly my fault.

I'd also like to acknowledge EllisLab and the wider ExpressionEngine community — I'm proud to be able to contribute to the community and appreciate all the support and encouragement I receive. Special thanks must go to Mark Bowen and Ron McElfresh.

Next, I would like to thank my readers: I especially want to thank those who take the time to get in touch and let me know what they like or don't like, those who submit errata, as well as those who take the time to post about my book on their own website or in a review on Amazon. One of the great joys of writing a book is hearing from people from all over the world, and from all professions.

Finally, and most importantly, I would like to thank my wife, Megan. There are not too many women who, in the final stages of their first pregnancy, would want to hear their husband say "Honey, right after you give birth, I was thinking I'd write a book..."
