Application "cover letter"?

<p>I can't apply ED/EA because I'm a transfer, but I have one school in particular that I really want to go to. This school doesn't ask for a "why us" essay. I'm wondering whether it's okay/good to send a short additional document explaining that if I get in I will definitely attend and why. What are your thoughts? Thanks!</p>

<p>I hate it when people do this, but... BUMP.</p>
