FlexCourse brings you Adobe Flex tutorials in PDF format for free! The goal of this project is to provide free Adobe Flex tutorials. The FlexCourses are written in the same way and with the same layout to make FlexCourse a consistant product. Each FlexCourse comes with the complete source code. So if you have trouble understanding the instructions you can simply look it up in the original source files.
FlexCourse is still in Beta which means the website can have some downtime/problems.
