<p>I would highly discourage from being pressured to send in a resume. That said, I do recommend using the additional information space to elaborate on an activity or a life situation. If your achievements fit the resume style better then go for it. But if you want to add more of your voice and character to the application, then writing something in more of an essay-form also works great. I did not include a resume and got into all the most selective schools, for example. I feel the resume format you describe leads to repeating things that could be easily included in the common app itself.</p>
