Promoting Free Software in my school

Hello everybody! It's my first mail in our mailing list.
In this year I will turn to new school. I watched homepage of this 
school and there's problem.
The oficial page is http://g1.swidnica.pl/ (it's only in Polish, then 
you may don't understeand it) and you can see in this webpage much MS 
Word documents (*.doc - maybe Word 2003) and it's problem.
I think it this school is used proprietary software... and... what I can 
do to promote free software there?
I want to this school move to Free Software, but what I can do? (of 
course if they will no want then I can't do nothing, but I think they're 
isn't know nothing about free software and I can change something)
And where start it promotion? Talk with director or with IT teacher?
What do you do to informating about free software in you school?

Or I must do anything about it? May it's only fight with windmill (i 
don't know what write it in English ;p)?
Greetings,
Sueroski


PS sorry for my English, but I'm young and I'm not from English-speeking 
countury then...
