This should be my favorite site for learning actionscript coz i've learn actionscript here. They list all article on which you want to learn, so you can jump ahead on the intermediate level.

This site is so cool coz it's less theory and will only teach you want you need to know. I highly recommend this site for people who hate tutorials that have too many theories and just want to jump into the real thing.

If you're like me who don't want to read and want to learn from audio or video, then gotoAndLearn is your destination.
