I just got out of college studying as a digital media major. I have only a few tricks up my sleeve when it comes to actionscript, but i will try to help anyone i can. I have mainly used 3.0, and am now trying to use 2.0 as it seems to me like some of the functions I want to to can be accomplished easer with 2.0. I know that i can use 3.0 to do just about anything 2.0 can do but on occasion it seems to create much larger files, and file size is everything when working with the internet.
