About the Authors

Karol Król is a WordPress developer, PHP programming specialist, professional blogger, and writer. He has been building expertise in WordPress ever since his early years at the Silesian University of Technology, Poland, where he graduated with a Master's degree in Computer Science. Early in his career, he worked as a freelance website developer, and then launched a web design business together with a close friend. Later on, he decided to shift his interest towards popularizing WordPress as the perfect solution for all web-based projects and devoted his time to growing his writing career. To this day, his articles have been featured on websites, such as About.com, Lifehack.org, ProBlogger.net, Freelance Switch, Quick Sprout, and Six Revisions. Currently, his main two projects are providing Online Business Advice for Normal People through his main website (http://newinternetorder.com/) and taking active part in the Writers in Charge project (http://www.writersincharge.com/), and teaching other writers how to take charge of their writing career.

Karol spends most of his spare time making music, training Capoeira, cooking, and drinking wine.

Aaron Hodge Silver has been designing and developing new websites from scratch since 1999, just before his graduation from Columbia University. Early in his career, he worked for several web companies and startups, including DoubleClick and About.com. Since 2004, he has been self-employed through his company Springthistle Design and has worked with a staggering variety of companies, non-profits, and individuals to realize their website dreams. In his professional work, Aaron's focus is always on usability, efficiency, flexibility, clean design, and client happiness. WordPress is the best solution for many of Springthistle's clients, though Aaron also develops custom web applications using PHP and MySQL. Aaron was the author of the two previous editions of this book! You can find more about Aaron's professional work at http://springthistle.com.
