I wrote a letter to a prelim program a few weeks ago expressing my strong interest and stating that they are my #1. I had every intention of ranking them #1 at the time. However, due to some very important unforeseen personal circumstances, I will not be able to rank them #1. Is this a match violation? Should I tell them that they are no longer my #1 or just let it go? They are a small community program in case you were wondering.
