Extension:UserSnoop

Description
The UserSnoop MediaWiki extension/special page

This extension creates a new special page through which a user with the appropriate permissions ('usersnoop' and 'sysop') can view and manipulate users.

The main section is display of user information: If the calling user is a member of the 'bureaucrat' group then they also can:
 * internal user id
 * username
 * real name
 * email address
 * whether the user has new talk or not
 * date of registration
 * number of edits
 * whether the user is blocked or not
 * block reason (if blocked)
 * list of *effective* groups
 * last update of user profile
 * user's signature
 * user's last login
 * force the user logout (boot user)
 * block the user
 * spread the block on the user to all of his/her ip addresses
 * unblock the user

The actions on information that can be called on the target user:
 * page views
 * page name
 * number of visits
 * last visit
 * watchlist
 * page name
 * last visit
 * last edit by user
 * last edit by any user
 * new pages
 * page name
 * create date
 * last edit by user
 * last edit by any user

Installation
