| <p>This page lets you turn filters on or off in a particular part of the site. | ||
| This page only gives you access to those filters that the Administrator has | ||

|

| <p>Some filters may also let you set local settings, in which case there will be | ||
| a 'Settings' link next to their name.</p> |
