the only way to do it is by using a pc spy like keylogger then upload on to the shcool computer(make sure its one dat da amdmin uses) and after u upload it a menu will apear and u type in ur email address and da program will hide and its un traceable so they wont find it then just log in to ur email acount and everything dat was typed in da computer will be in ur email then da next day log in as admin and download limewire and ur done

ps
i made a acount just to help u out
