If your admin hasn't updated their 8e6 blocked-site list yet, you can use that site to
get around 8e6.
If that site is blocked, then follow the instructions on Peacefire's page, setting up a circumventor. You can set up the "circumventor" program on your computer, and it will give you a URL that you can use to bypass 8e6 wherever you go.
