What about TLD?
I wouldn't worry too much about today being the cutoff day. For one, only one person has gotten an interview so far. You would think there are more Vandy applicants checking this website, so I feel reasonably confident that when interview invites go out, we'll see more show up on the results page of Grad Cafe. Two, today seems like a terrible day to call. Maybe they're going to email their invites, but I think Vandy is the type to call (assumption here). If they call and you don't answer, they're most likely not going to talk to you until Tuesday when they're back in the office, which is a long time to hold off a prospective student.
I feel like today is another day to spend waiting and Tuesday will be the more likely contact day.
