Waitlist Advice - Urgent!

Hello all - My D has been waitlisted at her top school and with it being her top choice, doesn’t want to seem like she is in any way shape or form lacking interest. How much is TOO much when it comes to communication? Who are the right people to talk to? She’s sent in a letter expressing her interest and saying it’s her top choice and she’s called to check up on it. Would a typed letter to the head of the department be necessary? What do we do? She’s been rejected everywhere except for this school, and it’s incredibly competitive so I’m not sure where she stands on the waitlist. It is also unranked, so I am not sure whether a boy or girl saying no means they open it up for both genders. Please help!! Thanks so much!

I also am waiting to hear from a waitlist I’m on -not MTbut performance…I was told right after auditions that I’m on a shortlist but I’m still waiting-even if I’m told no I’d like to know . Contacting them isn’t good I was told
