Extension:WhoIsWatching/en

The WhoIsWatching extension allows to find out who is watching a particular page, and add others to watchlist for that page.

Rationale
Even though this notion goes against Wikipedia and Wikimedia privacy policy, some wikis may actually like to see which of its users are watching particular pages. This extension provides just such an interface at the bottom of every page. Additionally, this extension has an option to allow any user to add any page to any other user's watch list.

Installation
Make sure that ist installed as it is a prerequisite for this extension to work.

Configuration

By default, users in the sysop group have permission to see page watchers and add pages to anyone's watchlist. You can grant these permissions to logged in users, too, or any group you think needs it.

Usage
This extension also provides the  parser function showing the number of watching users of   plus providing a link to. This can be used with skins not supporting footer links or to create the WhoIsWatching link somewhere in a wiki page.

Known issues
The first time after a you submit a request to remove a page from the users watchlist, the user is still shown on the form. To get around this it is disabled and displayed with a red strikethrough.
