lame tutorial with terrible layout...
if you are making tutorials on flash, you oughta learn flash yourself. it is NOT that hard to make a "radio" that continues playing, even after going to different frames. that happened to my main irk for this. the other one is that you said there was actionscript for advanced users, yet you only covered basics of flash and basics of actionscript. if you want anything to do with advanced, make a platformer or AI script. if you really want to go all out, experiment with NETWORKING. that would get you some major points from me, assuming you explain it good enough.
