Help with letters of recommendation!!!!!!!

<p>on the envelope for the teacher reccs should we:
1) put our address in the top left hand corner
2)put "Attn: Evaluation B" above the MIT address to send it</p>

<p>thank you!</p>

<p>You should definitely put a return address on the envelope in case there’s a problem and it needs to be returned by the post office, but whether you put your address or another isn’t particularly important.</p>

<p>You don’t need to mark the letters in any particular way. They will be opened and filed by mail room staff.</p>

<p>thank you very much!</p>
