ignore atrophicwhisper,
I know a friend who got off the waitlist.
What you need to do is contact them, preferably by email (I don't know how good of a speech-maker you are), and let them know that even though you were waitlisted, you still have WashU as your top choice, and that you would love nothing more than to be able to join them this fall.
Hit send, then cross your fingers.
best of luck!
