Update:
My wife met with the Principle while I was at work. here's the result. the Principle gave my wife a transcript of the facebook page that my daughter and her friends posted to. which I have since read

after my wife stopped laughing she was told that they will NOT be reporting my daughter, but did warn my wife against this type of conduct for the future and how it's "dangerous" so there will be no further action there.
On the teacher its a different story. apparently the faculty had been warned before the school year to not have ANY interaction Via facebook or any other social netwroking sight with any students. so the teacher will be getting a formal repremand in her file about this conduct. and the appropriate if it happens again speach.
Good thing for them I didnt need to go down there
Thx for the support Gents.
