Hagen Graf was born in July 1964. Born and raised in Lower Saxony, Germany, his first contact with a computer was in the late seventies with a Radioshack TRS 80. As a salesperson, he organized his customers' data by programming suitable applications. This gave him a big advantage over other salesmen. With the intention of honing his skills, he joined evening courses in programming and became a programmer. Nowadays he works in his wife's consulting company as a trainer, consultant, and programmer (http://www.cocoate.com). Hagen Graf has published other books in German, about the Apache web server, about security problems in Windows XP, about Mambo, and about Drupal. Since 2001, he has been engaged in a nonprofit e-learning community called 'machm-it.org e.V.', as well as in several national and international projects. All the projects are related to content management, community building, and harnessing the power of social software like wikis and weblogs. He chose Joomla! CMS because of its simplicity and easy-to-use administration. You can access and comment on his blog (http://www.bloghouse.org/en/hagen).
