I would suggest writing an update letter in the next few weeks with your recent accomplishments/activities. I would trend away from updates about grades because if you were able to get an interview, then your numbers are good enough for admission. But if you are a borderline applicant (numbers-wise), then an updated transcript can't hurt.
yeah seriously me too. i was waiting since aug 4 with two update letters to them too. =\
This goes to both sets of people (those on the waitlist and those waiting for an interview).
Don't send an update letter unless you really have something to update about your application. It should follow, of course, that you're actually doing something to add to your application since you submitted it this summer. If you're not, and you don't end up getting in anywhere, you'll be in a world of hurt (been there, done that). And, again, if you're borderline numbers wise, an updated transcript when all your final grades from the semester are on it, won't hurt. Unless, of course, your GPA drops as a result.
That said, for people on the waitlist... you're not going to see any movement until May. So make sure you cross your t's and dot your i's (include UVA on your FAFSA, make sure you have all your parent's financial paperwork together, etc). You can send update letters, but, again, make sure it's something important. That means that if you interviewed a week ago and were waitlisted, you should probably hold off on sending a letter for a couple months.
Come May, if you're still really interested in coming to UVA, send a letter of interest/intent. A lot can happen in that time.
For those who have not yet interviewed... treat every single interaction you have with the students and staff as an interview. The tour guides, your hosts, and the people who come in to talk to you have no real say in the ultimate decision that comes down. But, if you act like a complete jerk to one of the tour guides, they might let it slip to one of their friends on the admissions committee, who does have some say in the final decision. Similarly, if you really impress your host, they might pass on a good word for you, which can have some impact on their decision (especially if it's a waitlist decision). I'm not saying this to frighten you or make you into a complete brown-noser, but I speak from experience.
