Hey neelz, I had the same thing about a week ago, nothing seemed to be getting done, but when I called SAS (student accomo. services), bruce (first pref) and brugmann (second choice) within a day i was placed. Acacdemic offer made seemed to imply something like you're on a waiting list, there are no rooms, but we'll see what we can do. I could be wrong on everything here though, because my questions were answered with 'we have an accomodation guarantee for new undergraduates', although that only applies for main round offers. Maybe by calling my application was unlost and not allowed to languish? Apparently after applications are made through SAS, each college/hall has its own system of processing/filing applicants. So probably the best thing is to pester them, get in their hair until they let you in somewhere!
That's all I know, hopefully this has been some help to you. Good luck.
