heres the deal, my school uses BESS internet filtering across the network. Currently the browsers are set to use the local proxy 10.0.0.9:80 (the bess proxy). When i change this value to another proxy, it doesn't work. There must be another unblocked proxy across the network, is what im thinking..
http://cprox.netfirms.com
go there, that site keeps a usually updated list of cgi-proxies, it gives instructions on how to use many things like hotmail, geocities, google images.
i think some (tree minus stump)ing of some of those things you use to unlock doors might be neccessary. Find what im talking about, punch the answer to the riddle into google, check first result, you can figure out the rest.
