Umm... okay? Not quite sure what you thought I was trying to articulate but you're not wrong I guess, but that's an awfully strange way to put it.
The reason I'm remarking on it to begin with is because IU's website still says that decision notifications are sent out on the 15th of each month. Now, you're correct, they don't specify whether these notifications are electronic or physical, but they were electronic last cycle. Meaning, people who were accepted were notified on the 15th of each month because email is, well, instantaneous.
I just think it's kind of strange they would suddenly switch back to physical mail (which evidently is sent out on the 15th of each month, meaning applicants don't find until days, sometimes weeks, later) without so much as a peep to applicants when acceptances have been communicated through email the past couple of years- no need to read too much into it and turn it into a doom and gloom about how our health system is failing as a whole.
