Ya our district just got new computers too, heres a hint look at the back of the computers and take out the cord attached to the mouse and switch it with the computer's mouse right next to it, and sit around and wait for someone to take that computer and watch them all confullzed and try to turn their computer off and on. It is mean, but it is worth it

.
Also a little on topic ya school blocks weren't made to get around, but it doesn't stop you from doing it. I am a crackdown fanatic and when they blocked the official site I was kinda mad so I used a
program to get around it. It was blocked for criminal skills I wasn't going to stand for that, I am not however going to tell you what I used, its for me to know and you to ask all of your friends at school about.
