Is there grounds for libel?

A 12 year old classmate of my daughter made a web page naming my daughter and a fellow student and insinuating untruths. I called the mother and she has since taken down the web page her daughter made. However, I have a picture of the web page on my phone and pasted a copy to a word document that I sent to the appropruate school officials. My daughter is very upset and we are also upset. I just want to know my options should this happen again.
