<p>If anyone's submitted additional letters, is there a fax number you sent it to? Or an address to mail it? I'm having issues finding any means of sending them my additional letter.</p>
<p>They let you email it.</p>
<p>Hi Unsure!</p>
<p>I told my research mentor to mail it to 1 College Hall. You’ll be fine, though I believe it might get redirected to your regional officer and then back to Penn. But you should mail it to Philly.</p>
