This book is for any Flex developer who has mastered the basics, but wants to take their skills to the top level-it is packed with essential practical techniques in use in a professional production environment, which you can learn from and use in your own Flex 2 or Flex 3 applications. Assuming the basics, they take you through planning the project, wireframing and application design, putting the basic structure together (including the PHP and MySQL backend,) customizing the look and feel of the application (to make it not just look like any other Flex application,) and implementing all the killer features that make the RMX great, such as blog, wiki, content aggregation from RSS and other sources, video, audio visualizer, events calendar, and advertising mechanisms.
