Can't log into yahoo.com

If you have any Yahoo/AT&T email accounts (att.net, sbcglobal, bellsouth, even prodigy.net) then you should be logging in through www.currently.com.  If you go to yahoo.com and input a Yahoo/AT&T address, you'll get redirected to the AT&T login page.

The only people who should log into yahoo.com are those with yahoo.com addresss.

Even with a "yahoo.com" address I get redirected to currently, and it does not recognize my email address as legitimate.  I can still access the messages on myh mobile apps, but not from my browser!
