Within the site, you can provide a recommendation (i.e., review) of articles and products. This can be especially helpful for articles covering topics in your area of expertise, and products you specialize in or with which you’ve had a good experience. Go to the Feedback section at the bottom of each respective page. You have the ability to recommend (thumb up) or not recommend (thumb down), and to provide comments. When finished, click Submit. While your reviews are not housed in a central location, they will be posted on the respective page(s) on which you provided feedback.
