As you may have seen, work to perform the Wikimedia cluster-wide [[mw:SUL finalisation|single-user login finalisation]] (SUL finalisation) is taking place. This may potentially effect your work as a local bureaucrat, so please read this message carefully.
Why is this happening? As currently stated at [[m:Global rename policy|the global rename policy]], a global account is a name linked to a single user across all Wikimedia wikis, with local accounts unified into a global collection. Previously, the only way to rename a unified user was to individually rename every local account. This was an extremely difficult and time-consuming task, both for stewards and for the users who had to initiate discussions with local bureaucrats (who perform local renames to date) on every wiki with available bureaucrats. The process took a very long time, since it's difficult to coordinate crosswiki renames among the projects and bureaucrats involved in individual projects.
The SUL finalisation will be taking place in stages, and one of the first stages will be to turn off Special:RenameUser locally. This needs to be done as soon as possible, on advice and input from Stewards and engineers for the project, so that no more accounts that are unified globally are broken by a local rename to usurp the global account name. Once this is done, the process of global name unification can begin. The date that has been chosen to turn off local renaming and shift over to entirely global renaming is 15 September 2014, or three weeks time from now. In place of local renames is a new tool, hosted on Meta, that allows for global renames on all wikis where the name is not registered will be deployed.
