I wanted to mention that my friend and colleague Jonathan Kaye of Amethyst Interactive  and FlashSim  is having another series of online classes. A 5 week “Online Simulator Developer Class” starting March 21, 2005 – June 6, 2005. More information and signup can be found here.  Make sure to note that Macromedia User Group Members  (not just Philly members but most MMUGs) receive a special discount when registering for the class. I’ve seen some of the course materials Jonathan has put together and they are top notch. I’m not sure there is anywhere else where you would be able to learn this type of information that Jonathan has put together, if your in the market for creating simulations with Flash – this is the resource you should investigate.
