How to Update Spring Schedule?

<p>How should I notify Harvard of any changes in my spring schedule? I take most of my classes at the local community college and made a note in my application that the classes were subject to cancellation, which is exactly what happened with one of my classes. I'm a bit unsure about how to update my app with this info, since it's not anything really major and they probably get tons of emails. Thanks for any help!</p>
