Last year's was also a 3-page proposal, but it really is hard to find examples and/or tips for the application, because they've changed the requirements so much over the years, and NDSEG doesn't give application feedback the way NSF does. I applied last year as a first-year grad, didn't get it, gonna try again this year but yeah it's been hard to figure out what to improve upon.
Okay, this stress finally made me create an account so I could contribute- anyway, I haven't received an email yet either. I'm in Mountain Time. Received all past emails just fine, and nothing in my spam either.
