When I try to log in Yahoo does not register my name or my password. I've went to the Help link and typed in my question and they couldn't even come close to answering it.

This problem started on Wednesday afternoon; Wednesday evening I was able to get in and then Thursday morning the problem was back: not able to get signed in.

I know it's not my login/passward that's the problem, I believe they are trouble shooting but I would like to know what they are doing to fix the problem.
