Yahoo Shuts Down Mail Classic, Forces Switch
 

If you are an aficionado of the classic Yahoo Mail, get ready to switch if you haven't already. The official changeover date to move to the new version begins tomorrow. If you wish to access your mail after this week, you will be forced to upgrade to the new version of Yahoo Mail which may not sit well with many veteran users. Rock meet hard place. When you upgrade, you will be accepting our Communications Terms of Service and Privacy Policy. This includes the acceptance of automated content scanning and analyzing of your communications content."
