Are you seriously using ClipEvents? And teaching others to use them too?
ClipEvents are worthless except for some certain problems (like when applying actions to multiple MCs and a loop function will slow the file too much).
If anything to improve besides the approach of teaching - that'll be the presentation.
I don't many who want to learn from something that looks very amateur. Even if the tutorial can't be find elsewhere, presentation is crucial. This includes interface, graphics, structure, environment and language.
Not bad tutorial wise, but it could be spruced up a bit. Plus you should make it so that the page changes when you CLICK the button, not just pass over it, cause that gets really annoying.
Yeah, I Was Tired When I Was Doing tHis, And It Was My First tutorial. xD
