How to notify the college that i will not be attending?

<p>Is there any official way to let UCSC that i will not be attending? Or do I just email them saying so? I've been told that your supposed to notify the colleges you aren't going to attend so that they can offer your spot to people who are wait-listed, as well as it just being a common courtesy.</p>

<p>neeeeeeeeever mind. i found the “decline offer of admission” button</p>
