Messages in Mavericks has no Buddy List?

Can anyone who updated to Mavericks check to see if you have a Buddy List window in your Messages app (fka iChat)? I don't, nor is there an option for Buddies List window under its Window menu, as normal. The only window that opens is the Messages window, which works fine. But there's no way to see who's online, ones Buddies, etc.

I'm attaching a screen shot of what I see.
