How to Pin Feedback to your Profile
Pinning feedback serves two purposes: it helps showcase the awesome feedback about your editing skills, and it can help push down any (hopefully uncommon) negative feedback you may have received.
To have your most awesome user feedback appear first on your profile, click "Edit Profile" in your dashboard menu.
When you scroll down to see your feedback, you'll see stars next to each entry. Stars that are filled in have been pinned to the top of your feedback list, and those that are not filled in have not been pinned:
All you have to do it click a star to fill it in and pin it to your feedback list. This will push is closer to to the top, meaning it will have greater visibility to customers who visit your profile. For good measure, I would recommend pinning positive feedback that has a name associated with it, if possible.
