You are able to leave feedback for someone you have worked with in the form of a recommendation. Recommendations can only be requested or added by the person who controls that particular profile page.
If you would like to leave a recommendation for someone, contact them directly and they will be able to start the process for you.
When setting up a recommendation request, you must first sign in to your account and go to the Recommendations page (accessible from your Home page or My Profile page). To send a recommendation, enter in the first and last name of the recommender as well as their email and click “Add.” This will automatically send an email to that person with a form to complete.
Once the recommendation has been completed, it will appear directly on a user’s profile page.
