Right. You can't check the waitlist per se, but if you see that the reservation you had been on the waitlist for is now on your list of current reservations, you are essentially checking the waitlist in an indirect way.
When the information first became available on the DVC website, I checked and it showed my VWL ressie. Just this morning I checked it again and it now shows BWV. That's how I know my waitlist came thru.
