I found this great article on Six Revisions site. They have 12 weblinks to flash learning sites that can definitely help the beginner to advance level flash designer. If you have some time check them out. I personally really like gotoandlearn with Lee Brimelow. His easy videos stream fast and they are very easy to follow.
Click on the link to goto Six Revisions site for the 12 websites.
