Thats weird. I know several of the finalists, and they all got an email, one way or the other. I also remember 1 person posting that she got a rejection email and she was NOT a finalist, so obviously the system is not perfect.
Your email may have gotten lost in cyberspace, or maybe there was a mistake and you weren't notified. You might try emailing them and asking for clarification, just in case. The email address is beadstar@interweave.com.
