My Quest

I am on a one-woman quest to stimulate correct usage of the apostrophe. the poor thing is forgotten both far and wide. i was just at curriculum night at my daughter's school, and the presentation included "eagles nest", "principals award", and so on. drove me nuts. i understand that language is in a constant state of flux, and the apostrophe will probably soon go the way of the dodo bird. still. one would hope that those in charge of teaching our children would know the correct current usage.
my dilemma is, how in the world do i correct the presentation without alienating the staff and teachers at the school? maybe an anonymous submission under dead of night...
