The New Students Manual was sent out last week, so you should receive it soon; I received my copy today. It includes a Roommate Referral Form, which you can send in if you would like to be matched up to a roommate (though this isn't guaranteed).
It also lists a couple of places to live near campus:
- The Triangle
- Waldorf Tower (15 min walk)
- Kensington Place (10 min drive)
It also has numbers for various housing services near the campus.
