I don't think you'll receive an email that your app was received. I'm pretty sure as soon as you created a username/password they already had it. You were simply updating it when you filled it all out.

Whether you'll receive an email or a phone call for the invite to Dallas is anyone's guess. It wouldn't have surprised me if they had started sending out the invites today, but if no one has received one yet ... probably not. My guess is they'll start going out either later this week or Monday next week.

Best of luck to everyone that applied!!
