Thanks to all for the posts. Just got an alternate/hm (dissertator) letter-postmarked April 7. As I see folks posting what they received, it makes me curious. How many alternates are there? Others have said there is a list/ranking for major fields, but not total numbers. I suppose there is no way to find out, except to (im)patiently wait for another month to hear back or hear nothing at all. Good luck to you all, and congrats to those who have heard positively from the Ford and others.
