I would like to thank all the team at Packt Publishing Ltd., who worked with me as an incredibly helpful team. Sarah Cullington helped me to transform the original idea in the final book and to give my first steps working with a Cookbook. She was always ready to help and give good advice when I was doubtful. Zainab Bagasrawala guided me with patience through the process of writing. Swapna Verlekar also guided me in the development stage of the book and added wise comments to my original writings.

I would also like to thank Paramanand N. Bhat who has performed a great job as a Technical Editor, the reader will notice his work.

I wish to acknowledge my Reviewer, Ben Reynolds who has been very helpful with his comments and gave me good tips which I added to the different chapters. I must also thank my Proofreader Kevin McGowan for his thorough reviews.

I would also like to thank all my students, either real or virtual, who made it possible for me to be a teacher.

Special thanks to my five-year-old son, Nico, who despite his age was very patient and supporting in the writing process of the book, even though he does not want me to work at all! My parents, Susana and Jose (also a writer), who always stood by me and supported my decisions. My brother Gastón C. Hillar who helps me whenever I need him. My little one-year-old nephew Kevin and my sister in law Vanesa S. Olsen with whom we spend time working and exploring Moodle and Web 2.0 resources.

Many thanks to all my relatives, friends, and work colleagues who have helped me in different ways throughout the writing process of this book.
