No, the person on the phone said the portal will be updated for all at the same time and I just double checked and no portal update so it seems they are for sure sticking to a set 7pm CST deadline.
Saw the email and got a call today (from a 779 number) w/ an acceptance message and funding info (10k initial offer). I am sure they are making the rounds on calling folks so I would make sure to answer your phone if you can today if you see an IL number. Wishing everyone the best outcome on admission and funding!
