How to disable SmartFilter

First try to access
If your admin hasn't updated their SmartFilter blocked-site list yet, you can use that site to get around SmartFilter.

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 SmartFilter wherever you go.
