Half my school knows about the PHProxy i run, and the admins are either too lame or too stupid to do anything about it. However, most people just install Firefox into their profiles, which is easy as hell to do once you get the installer.exe file. Then again, our url blocker blocks exes and anything to do with Firefox. (For which reason i also have a zipped Firefox installer on my proxy page
)
Myself, and 2 friends I trust use a little program I wrote which disables the proxy in the registry (in vb6, which they teach us), so we look like "good students" who don't "bother to get around the proxy by using Firefox."
