how can i create a tutorial for my system using flash?

Answer 1

You should do it using the power of ActionScript surely,
the more you could use actionscript, the more your job will be interesting.
try to make some interactive objects (eg. tutorial movies) in it.
if you need some help, i will be very glad to do that.
if you dunno flash, again, i'll be glad to do it for you. ;) :)

Answer 2

Do a search for viewletbuilder.
