What's interesting is that I got the SAME letter as Muppet:

Dear XXXXXX:
On behalf of the Admissions Committee, I am pleased to inform you of your admission to the Class of 2008 at Stanford Law School. A package of admissions materials will be sent out to you today.
While I would have certainly enjoyed passing along this bit of good news to you personally, I was not successful in reaching you by phone. So, via e-mail, please accept my congratulations on your admission.
Do not hesitate to contact me should you have any questions about the Law School.
All best,
Faye Deal
Associate Dean
Stanford Law School

The part about calling is weird if they don't really do it (didn't for me).
