Yes, I checked. And I personally know another winner who also has definitely not received an e-mail. I'm not sure what the deal is. Some friends who won last year say it took them 3-4 days before they got their e-mail after the NSF publicly posted the list and a note about e-mails being sent. Unclear if they are as bad about sending rejection e-mails.
FYI - I received an award but have NOT gotten an e-mail, so there probably are people who have been rejected who have not gotten e-mails either who they intend to notify very soon. Good luck all.
