Now that the pre-release secrecy has been lifted, I can begin talking about Flash Catalyst more. A great place to get started is Adobe’s help:
Although Catalyst is not shipping just yet, you can still view some “getting started” tutorials at: http://labs.adobe.com/technologies/flashcatalyst/tutorials/
Finally, you will want to make sure you watch the forums: http://forums.adobe.com/community/labs/flashcatalyst
If you find great Flash Catalyst resources, tutorial, make sure you let me know! Together we can help the Catalyst community grow!
