My son is still [anxiously] waiting here in California. Mail carrier just came; no news. :-( He E-mailed his admissions officer and she said the Academy's "postmark deadline" was the January 20. Hopefully tomorrow will bring good news.
As far as I know, all EA notification letters were mailed by Friday, 1/20. I would recommend contacting your AO (or you can send me a pm) if you know that your record was reviewed in EA, but you haven't received your notification letter by Friday, 1/27. We should be free to share decisions via e-mail by then.
