I've called them and basically the answer was 'that's great for you, and we'd love to offer you funding, but we simply do not have the funds available to offer anyone funding, let alone you.' I just thought of something new.. should I call Tech and be like blah blah UVA, and see if they bump the offer? Or why fuck with a good thing? I don't know if they even can bump their offer. Call them and tell them you have an unfunded offer from UVA. Ask for more money and see what they say. I'd bet this will be an awkward conversation.
