The Parental Control feature lets you set a list of allowed or restricted Web pages, regardless of the type of filter applied to each user. To configure this aspect of the Parental Control, follow these steps:
Click Parental control in the main window of the program.
Make sure the Enable Web content control checkbox is selected.
In the Website whitelist and blacklist section, click Settings.
The window displayed contains two sections: List of allowed Web pages and List of Web pages to block. If you want to specify one or more Web pages to which the user cannot access, regardless of the filter applied, add the addresses in the List of Web pages to block. If you want to specify one or more Web pages to which the user can access, regardless of the filter applied, add the addresses in the List of allowed Web pages.
The options available are:
Add a Web page to the list: To add a new page to either of the lists, simply click New Web page and Add.
Remove a Web page from the list: To remove a page from the list, select it and click Delete.
Once you have established the settings, when a user tries to visit any of the pages on his/her blacklist, a message will appear informing them that they do not have permission to access the page.
