Ok, so in my school proxies work, but only until the admin's block them. however, if we made a list of newly formed proxies yet to be unblocked, we could simply acess them at school and the next day have a new one.
There's a way to do it with google, and you ethernet cord that cant be blocked, has something to do with www.google.com/xhtml but i cant remember how to do it. I also got suspended for doing this cause my schools gay but whatever.
