<p>So I was admitted ED, and I finally saw the housing/dining application on the welcome page. Here were the instructions given:</p>
<p>To complete the application, please first visit Tips for Completing Your Housing & Dining Application and then log-in to the First-Year Housing & Dining Application using your Columbia PID (C123456789) and birth date as follows (mm/dd/yyyy). </p>
<p>Is the PID the C00...? Or is it something new? Because my ID didn't work...</p>
<p>Thanks!</p>
<p>Oh, one more thing. Will early decision accepted students get more info and stuff in the mail? My welcome package in December didn't have much info in it.</p>
