Ideally, each applicant would submit himself/herself. If you are in a position where you, as an instructional technologist or a co-applicant, have to submit for someone else, follow these steps:
1) Create a profile for the applicant: log out of the site, create an account and a profile for the person. Make sure you user a user name that makes sense and a password that the person can remember.
2) Log in as this newly-created user to submit the application form.
