Extension:Renameuser

Renameuser provides a special page which allows authorized users to rename user accounts. This will cause page histories, etc. to be updated. If you want to rename an account "into" another one, you need the User Merge and Delete extension.

Installation

 * 1) Download the files from SVN or download a snapshot (select your version of MediaWiki) and place the files under $IP/extensions/Renameuser
 * 2) Add to the end of LocalSettings.php (MW 1.17+):
 * or add to the end of LocalSettings.php (Special:Renameuser page
 * 2) Enter the name of the user to be renamed, and the desired new name, toggle the options to move user/talk pages and their subpages and to create redirects as desired, and click OK

The user will be renamed, and (if the appropriate option was checked) the user page, user talk page and all their subpages will be moved as well.

You can grant other groups the right to rename users, for example:

Notes:
 * If CentralAuth is installed, you'll get a warning if you try to rename a local user from an account attached to a global account or to a username reserved by a global account; a check box to rename anyway will be provided (this requires caution).
 * You won't be able to rename users to invalid usernames (which doesn't equal usernames which match a blacklist but includes for instance reserved usernames).
