The Internet Ratings Wizard is a plugin, available from the Tools menu. It aids in generating a PICS site rating tag for your document.
The Internet Ratings Wizard is very simple to use. In each step, you are presented with a rating category. If you would like to be rated in that category, move the slider to specify a rating. The rating's description is displayed as you change the slider value. Once you've completed all the steps, the wizard generates a PICS META tag which should be placed in the HEAD tag block of your document.
