<p>If one was waitlisted, how do you respond? I can’t even find the letter that waitlisted me :(. should I just email them?</p>
<p>i am curious as well</p>
<p>The real, paper letter that they mail you includes a card on which you respond and mail back to them.</p>
<p>OP - if you meant you <em>lost</em> that actual letter/card, then you should just write them a short letter stating that you wish to accept a position on the waitlist.</p>
