Don't hold your breath. They've been saying for years now that they are going to have internet access, beginning first with just the capability to check resort availability and eventually be able to do more than that.
Nothing yet.
Of course they do have the reservation request you can make using the member's website, or you can e-mail, but both of these are simply requests that requires a CM to get back to you. Neither is any type of on-line booking such as you can do for many hotels, car rentals, airline tickets, etc.
