I think they're making calls again, b/c a friend of mine who'd gotten a voicemail yesterday got the follow-up call just a few minutes ago.
As for the facebook group, last year Yale admitted 25 more students than normal, so that might explain the increase? Also, bear in mind that there are people who are deferred, deferring, and from previous years in the group, so I don't think the group size is a very great estimator for the actual number of admitted students in the current cycle.
And re: Shaws, I certainly didn't mean to suggest it was just due to Yale students. I only meant to say that they, among other community groups, we involved in getting Shaws to come to New Haven. Good to know.
