Common Tweening Tips/Tricks/Mishaps?

Hey everyone,
I’m compiling a list of common tweening tips/tricks/mishaps for an upcoming tutorial, and I am wondering if you have any to add to what I have come up with so far: http://www.kirupa.com/developer/flash8/tween3.htm

Do you all have any suggestions as to what else I could add. Replace tween3.htm with tween2.htm or tween.htm to see the earlier pages (also unfinished).

[size=1]EDIT: The above tutorial works, pretty much the same, in MX and up. So don’t be afraid to chime in if you have never used Flash 8 :)[/size]

Thanks!
Kirupa =)
