In reply to 'Hilda': Thanks for all your advice.
It's been a nightmare for my daughter - we've found out that one of the parents has been distributing copies of the alledged comments to my daughters friends parents, and as a result she's being ostricised!
So far we've haven't even seen what she's supposed to have said. The only access my daughter has to the internet in at my work, when I'm present - as she sits next to me, I can see what she is doing and she's only been on MSN twice in the last four weeks.
Our home computer is out of action, since we found out it was riddled with 'spyware' after we converted to broadband - as I omited to enable the firewalls, and didn't have anti-spyware. We formated the whole drive and so far haven't reloaded any software.
My daughters a nice kid, who can't sleep, doesn't want to go to school anymore.
I just can't beleive the vindictiveness of these parents
