The GRFP main page (login screen) disappears, and when it comes back up it will feature a new awardee list. So the blank page is what you refresh, if I remember correctly.
I went back and looked at last year's - it does seem to go down right at 8, although there's a lot of compulsive refreshing that happens for a few hours afterward.
Kind of wish it wasn't spring break so I would have deadlines to make me focus >_<
I've been working on my lit review for the proposal I submitted and am getting progressively more forlorn because I feel like I should have cited a billion more articles.
Sigh. Hopefully they announce it on Thursday so we can move on with our lives!
I think the subject line is different depending on whether or not you get it (last year I applied and didn't get it, and the subject line was "2012 NSF Graduate Research Fellowship Program Notification.")
Good luck everyone!
