Do you have a recent reference within the last year? That'll work too!
First things first, make sure you're on your Profile page. You can fill out a reference request from 2 different places:
By clicking into each outstanding item- Primary Reference & Secondary Reference
Scrolling down to the References section and clicking the Add (+) icon
Scroll down to the bottom of the pop-out, then click 'Already have a completed reference form?'
Enter all the information for the required fields and upload a PDF of your completed reference form. When you're done, be sure to save by clicking 'Add'
