Ok I know what you are thinking...why is he bookmarking a flash reference site - flash in a web programming class? Well I decided it was important to bookmark the ActionScript reference page because the structure of ActionScript 3 is similar to javascript used in many webpages. No, you don't need javascript to create a webpage, but adding it can allow for additional site functionality. It is also important to know the potential of integrating flash into a website and allowing for variables to be passed form the webpage and communicated to the flash movie.
Not sure if this will be useful in Module 1, but I've used this for adding Flash, ActionScript, and Photoshop content. Don't sleep on this site because they offer video tutorials that walk you through each step -- very helpful to "shadow" these instructors.
