They send it to everyone. They are very strong proponents of the no prematch contact philosophy. They used to send nothing but have settled on this letter as an alternative since many good candidates thought they were being blown off by the lack of contact before the match. In fact, when I matched there I called them prior to the match and asked what the deal was since I had other programs calling me and paging me all the time but I hadn't heard a thing from Denver(my first choice at the time). They basically said, "No comment"
