Why
You say yourself, 'this is the BASICS'. Ie. anyone with half an ounce of intelligence could figure out how to animate fire - and better than that mind you. (It's better if the 'slithers' of fire sorta bubble up in about 4 frames, rather than jumping side to side). I was thinking, oh cool I'll learn how to animate really sexy fire, but no! You should really teach how to use the mouse and open Flash first, that's about the level of this. Come on man!
