Extension:ReassignEdits

The ReassignEdits extension provides a special page named "Special:ReassignEdits", which allows permitted users to reassign edits from an old user to a new one. In opposite to Renameuser it does not rename users, just allows reassigning user edits. You can reassign edits from a non-existent user to an existent user or from IP address to existent user. It also allows merging logs (executive user and log title). By default this permission is assigned to the "bureaucreat" user group.

This extension is based on Renameuser extension, but is not dependent on it.
