How to switch back to Yahoo classic

Hello,
I switched to new yahoo because it promised I could go back. I want to go back, but I can't find a way. Every suggestion I see says to hit options and then, whee it doesn't matter what to do next because I don't have anything that offers options, mail options, or anything on the site that says options and nobody says where it is. It isn't in settings or anywhere that I can find on my page.
