A proxy is used to hide your IP address from others, thus letting you surf in stealth -- and because it hides your IP, it can be used to bypass internet filters at school or work. Your IP is hidden, and so your open to access any websites you like, and have insurance that they will not know it was you. All you have to do is enter the address of the site you wish to visit in the box, and hit 'Surf' -- and there you have it, you can unblock myspace!
