Vanderbilt, Michigan, UVA, and Washington University all honored my request for a fee waiver.
UVA dude was no effort, and it was at a law school fair. Michigan woman was talking me into applying at the same fair, and said that to prove that I really had a shot that she'd waive my fee so I knew it wasn't just to get more applications. WashU was via email request. Vanderbilt was from my conversation with Mike Spivey (now at WashU) at the same law school fair. He wrote down my name and told me to email him with a reminder request.
