Natalie MacLees is a frontend web developer and UI designer. She spends her days on the product team at Geni (geni.com), a Los Angeles-based startup that is crowdsourcing the creation of a single family tree of the world. Together with Noel Saw she heads up the Southern California WordPress User's Group (socalwp.org), organizing WordPress meetups, help sessions, and workshops. In 2010, she worked as a technical reviewer on WordPress 3 Complete by April Hodge Silver. She makes her online home at nataliemac.com.

Her obsession with the Web began when she bought her first computer in 1996 and promptly used it to build her first website. She spends the few moments she manages to be offline each day watching baseball, crafting, reading, baking, bellydancing, collecting Hello Kitty items, and avoiding avocados and olives at all costs. She lives in Los Angeles in eternal hope of developing so many freckles, they'll all touch and make a tan.

Gracious thanks first and foremost to John Resig and the rest of the jQuery team for creating and sharing such a useful and elegant library with the rest of us. Thank you to Houman Allahverdi for being patient while I spent so many hours at the computer, telling him to turn off the TV so I could concentrate. Thank you to Anna Motzer, Mark Tapio Kines, Tammy Wilson, Kimberly Wilkinson, Vanesa Rey, Marlene Angel, Trisha Marcy, Ed Doolittle, LeHang Huynh, Marco Hernandez, McCabe Russell, Teresina Goheen, and Ninno DePatrick for their support, advice, and cheerleading —I couldn't ask for better friends. Thank you to my sisters, Stefanie Elder and Bethany MacLees for being properly impressed that somebody wanted me to write a book. Thank you to my mom, Patricia Demby, and stepfather, John Demby, for being proud of me no matter what. And finally, thank you to Diane Colella Jones for believing in me, even before I did.
