This is from the email I got
"Entrant notifications are being sent in staggered groups, but if a large number of entrants are attempting to access the software at the same time you may experience slow speeds. If this is the case, you may come back later to finish your entry payment, so long as it is completed by the deadline of 11:59 PM Eastern Standard time on Friday, February 12."
I believe the 12th is your deadline. If I remember correctly when we registered, we were told that we would be notified by the 16th. I've been notified, but it still may take a few more days.
