5. Click the Web Site Exceptions menu option to specify certain websites that should always be blocked or always allowed, regardless of the status of the content categories that they fall into. Enter a URL in either category and click Add, then Save Changes.
6. The Blocking Effects option allows you to determine whether the program makes a noise when a site is blocked, as well as whether the admin override option is displayed. From here you can also specify a time-out of web activity when certain actions take place, such as attempting to visit 10 blocked sites in 10 mins.
7. If you want to refine settings even further, you can enter specific keywords that K9 will block even if they do not fall into the general content categories monitored by the program. Select URL Keywords, then type in address tokens (words) that you wish to prevent from loading in the browser.
8. Further administrator modifications can be found under Other Settings. Options here ensure that Google Safe Search is turned on and allow you to participate in the K9 beta, for example. You'll find options to change your administrator password and the email address that notifications are sent to.
