I was another of the 14 who attended UVA's visitation weekend. Like fangsout, I was admitted in early February with TA funding (the unofficial department email came on Feb 1, with the funding details sent by USPS about a week later). I'm going to visit UNC-CH on March 25, so I won't be able to make a decision until the end of the month. (My interests are theory, algorithms, and computational geometry.)
