So... I got this email from NDSEG today:
"This is a reminder that you still have not accepted or declined your NDSEG fellowship offer. Please make sure to accept or decline our offer by tomorrow, Tuesday April 7th. We have also received several inquiries from award winners waiting to here back from NSF. If you are waiting for NSF, you can have a few extra days to make your decision, however please let us know by Friday at the latest. If you fall into this category, please send us an email stating you are waiting for NSF. Those not waiting for NSF must respond by tomorrow."
Maybe this means NSF will be out by Friday? I mean why would they change the date if it wasnt going to make a difference?
My guess: Friday 2PM.
