This will be posted to Village Pumps on Wikimedia projects with bureaucrats on Monday, 8 September 2014. Please translate this message into any other languages you know to help our communities.
Single-user login (SUL) finalisation's goal is so that every Wikimedia editor has a single, recognized global account with one username across all projects. As you may know, after a long delay, it's now underway as an effort between bureaucrats, stewards, and Wikimedia Foundation engineers. This will also allow for development of cross-wiki tools like global notifications and watchlists. There is no set date for the completion of single-user login finalization at this time.
The process involves changing all rename processes into one global renaming process. The ability for local bureaucrats to rename users on this wiki will be turned off on Monday, 15 September 2014, as one of the first steps. Global renamers are in the process of being created to make sure projects and languages are represented by the time this occurs. I sent a note to every bureaucrat about this process three weeks ago with an invitation to participate and many have begun requesting to be a part of the group. Together with the stewards, the global renamers will be empowered to help editors work through the often difficult process of getting a global name.
In parting, visit Special:MergeAccount to unify your account if you have never done so. If your local pages about renaming still need to be updated, please do so and consider pointing people to m:SRUC for future rename requests, especially if this project does not have bureaucrats that hold global renamer permissions. If you have any questions, you can read more on the help page on Meta. You can also follow the technical progress on mediawiki.org. Contact me on Meta any time with questions as well. Thank you for your time.
