Hi all,
The much awaited, much anticipated migration of all accounts to global, also known as single-user login finalization, is currently underway. The process is expected to take about a week, but clearly it's never been done before so that is an educated guess. You can read a narrative for background, context, and what's actually occurring in this blog post (in English), put up yesterday: < https://blog.wikimedia.org/2015/04/14/single-user-login-for-all-wikis/%3E
A multilingual help page and FAQ about unified login is here: < https://meta.wikimedia.org/wiki/Special:MyLanguage/Help:Unified_login%3E
Please help spread the word with your communities as appropriate.
I'd like to extend thanks to all the staff and volunteers that have put so much time and energy into making this happen, the list is extensive and my gratitude is with you all.
