An Account Administrator or Event Administrator can make a submission on behalf of a Submitter by clicking on 'Submit on Someone's Behalf' in the event dashboard.

Enter the Email address of the person you are making the submission on behalf of.

Complete the relevant fields then click 'Save'.  The Submitter will receive an email informing them that a submission has been made on their behalf, which they can log in and view/edit.

Note:  When viewing All Submissions or looking at reports, the submitter you have submitted on behalf of will be shown as Unregistered until they register in the system.
