I bet a ton of you already know this but if you go to a school or your workplace that has sites that are blocked.. like NS for example.
you can type in your browser www.hidemy.info
if this wasn't blocked which it shoulnd't be then you can go to the browser on that site and type in your blocked site and voila net surfing blocked sites at school and work!
another site that is similar is www.allaboutabe.com
then you can press the picture of abe lincoln to get past the firewall. it looks like an educational american history resource site but reall it isn't.
I hope I helped those who didn't know about this out!
