One of the more convoluted announcements I've seen. I have to be aware that yahoo officially communicates via tumblr.com, check two different announcement pages which may not yet be up (converting time zones). When I clicked one of them I had to find the notice "in my region" which had only one option (not my region) and linked to another (non-yahoo?) site with an image of a document. I can't imagine all 500M users will jump through these hoops and remember when they last changed their password.
