i tend to think that screwing up is the best way to _quickly_ learn anything on computers! that way you lose the fear of screwing up....

worst thing i did was when i first got a used system- an old win95 box. i was cleaning out all the garbage, moving in, and i'm saying to myself "bin?!? what's that? well, guess i'll just delete it..."
:-)

boy, didn't i learn FAST. much better now, thanks.
