Simply email the amazing individual in charge of editing your admissions website and ask them to add ZeeMee to the application checklist. You can borrow Elon's language below or use whatever works best for your school.
Just in case that text is too small to read, it says:
Introducing ZeeMee: At Elon, we’re setting our sights higher. In an effort to get-to-know our applicants, we have partnered with ZeeMee, a free service that helps students bring their application to life. As part of a holistic review, we are committed to learning about the person behind the application. Simply copy and paste your link into the Elon University application. Sign up at ZeeMee.com. Please note, submitting a ZeeMee profile is completely optional and evaluation of your admissions application will not be delayed as long as all materials are received by the stated deadlines.
