<p>^^ Is it necessary? I already wrote one for the initial waitlist, and now that I'm still on the waitlist, should I send a quick letter in? Or simply respond?</p>
<p>I want to show "continued interest", but the fact that I am remaining on the extended waitlist is a bit self-explanatory, right? Or am I being too naive?</p>
<p>If you have some significant accomplishments, make sure to contact the admisisons office and let them know that. It can only bolster your case. Not sure how long before they notify everyone so sooner is better.</p>
