BTW for all you non tech minded people the url is also known as the address (in this case the address is www.myspace.com)
Step 1: Get to the Right Portal
Schools block proxies and you can got in serious trouble using one
use you knowledge for good and not evil!
I suggest searching "php proxy sites" on google as schools are regularly updating their blocking lists and what works today may not work the next
Step 2: Enter Site
I used www.browsetool.com but they all generally use the same interface
Step 3: Blast!
Once you have entered your url hit browse
Step 4: Voila!
