I think that this kinda stuff shouldn't be discussed on the forums. Or any forums for that matter;
1. Fucking with your school computers is a bad idea, you can be blamed for some pretty serious shit
2. If you cant get past your schools absolutely shitty (lets face it everyones schools is :P) computer security then really I and a good many people have absolutely nothing to say to you... except RTFM!!!
3. Holy shit, please, please, please tell me you know how to get past a simple web censor.
Im gonna go ahead and leave this thread before it makes me cry some more.
EDIT: Mad props to jjhappypants and DarkBlueBox for those wonderful guides :P
