This is my second book on Community Server. It covers much more advanced topics than the first book and is largely intended for developers. It will not only teach you how to create a theme for Community Server, but also how URL rewriting works, how to create custom Chameleon theme controls, and much much more (including some Silverlight fun). To find out more or order a copy please visit http://www.amazon.com/Professional-Community-Server-Themes-Programmer/dp/0470182083/ref=sr_1_3?ie=UTF8&s=books&qid=1219291694&sr=1-3.
