A student posts false, damaging info about a teacher on myspace. A case for libel?

Maybe a case for libel, but the damages here are probably not that great. Students have since Aristotle's and Plato's time said bad things about their teachers. Instead of writing on the bathroom walls, today it is on a social media site. The better thing to do is inform the shool's administration of the statements, with proof they are false, and allow the school's administration to handle this.
