my school blocks everything too. The only things we had left were youtube and popcap games, But they just blocked those too. and now that google video is in conjunction with You tube, you cant go to google video either OMGOSHH!
my school just disabled any part of the internet that had a "reply" to a forum kinda function. this may have just been a shitty internet connection day, but im not sure.
im pretty sure im the only person at my school with an account though.
