I want to learn how to use it to make a flash intro for my website. Anybody use it before? Anybody know any good online tutorials?

flash mx comes with tutorials.
just go to Help > lessons / tutorials there will be some there. they show you the basic's. very good help there

Those tutorials teach you almost nothing BUT the basics of basics... the best way to really learn it is probably simply play around with the program, don't be afraid to try different stuff, u'll come out with surprising results...

flashkit.com has hundred's , if not thousands of different tutorials, downloads, tips, how-to's, and one of the biggest message boardso n the internet

Thanks for the replys. I'll have to mess around with the program to see what I can do.
