just noticed a couple schools missing:
stanford - some by phone, some by e-mail (saying that they tried to call, when really they usually didn't)
chicago - phone call, followed by e-mail
for boalt, i would add phone call as a possibility (they e-mail if they don't get a hold of you)
UCLA - e-mail, but javert got in without one
that's it of the ones i applied to, and i wouldn't trust myself to remember the rest properly.
