ok I'll make the story short

I am in a fight with a girl from school for over 2 years now!
I decided to make a website about here, where I call here a hoocker (which she is, matter of speech) and included here tel number, mobile number, and made a little screen where you can enter remarks which will be send to HER email adres

well maybe I went to far, but she did some nasty things to me too

the problem:

she reported this to the police, I am shutting everything down
but should I be afraid for the police, can they find my IP adres??
does hotmail register your IP adres

plz answer this question, without making arguments about that I was wrong blabla (many people do!!)

cause I am not feeling really happy
