Sunday night @00:00 (Tynon send out a little mail) enrollment opens and Monday night @00:00 enrollment closes, and on a side note this is not your timezone time it is your SERVER TIME - And yes I tested this out just to see the enrollment button grey out and realising that I didnt sign up (yes very clever indeed)
I know this is not right because I have enrolled on Monday morning a few times. Also, there tave been a few times when Tynon forgot to send out the note.
