<p>If an acquaintance of mine has written a supplementary rec for me, how do I check whether my supplementary rec has been received or not? Should I call them? When Harvard sends you a postcard or something that tells you your application is complete, does it tell you how many recs it received?</p>
<p>You need to include a postcard with each recc so harvard can send
it back to you. Write down the name of your recommender on the card.</p>
<p>Lol at the OP's screen name.</p>
