Here's a trick I used to find who my GC roommate was (since housing never did tell who my roommate was):
1) Go to http://search.princeton.edu/search.pl
2) Search for yourself so that you can find the phone number of the GC room that you are assigned in
3) Now search for that phone number to see if anyone else shows up
Not sure if it still works but you can give it a try. Also I did this in August; not sure if new graduate students have been added yet.
Adding to the stats here: I received an award notification email yesterday (Saturday) at 3:34 PM EST. I'm 100% experimental and have a feeling my funding agency is most likely ONR. I can also confirm that the http://ndseg.asee.org/award/ page has some coding issues, as mentioned by a previous poster. Good luck to the rest of you who are still waiting!
I am finishing up undergrad at Chapel Hill right now. In my opinion, Chapel Hill does get boring after four years because there's only so much to do on Franklin St. If anyone has any questions feel free to PM me.
