ok so when you log into the schools computer open up notepad and type this in:
@echo off
Start
Exit
save as a "w/e".bat file on the DESKTOP
that will open cmd.
type into cmd then:
ping www."website needed".com
you will see [34.243.2432.55] random numbers in between []. open up google chrome, firefox, BUT NOT EXPLORER and type in the #. and your in.
i have tryed this with facebook, myspace, youtube, etc.
also try
httpS://www.youtube.com which works too. the "S" is the important character to rememeber here.
