When the tab is viewed it will display a grid of users who are watching the page. Each result will display the username, user real name, and page name. Usernames are linked to the same watching page, but will display all pages that the user is watching. Page names are linked to the same page, but will display all users watching that page. This installation will provide access only to group, sysop.
