Switching from Regular Decision to Early Decision II

<p>I'm trying to switch my application from Regular Decision to Early Decision II. I submitted my application about 2 months ago and now I want to switch it. I emailed Colgate and they said that it's possible to switch it using the common app (by sending in the early decision agreement through the common app), but I seriously can't find out how. I'm pretty sure I need to fax in the early decision, but the college admissions person seems to think I can send in the agreement through the common app. Anyone know how to do it through the common app? It would be much faster because I'm on break and can't see my counselor face to face but she is answering emails.</p>
