You may add a review for a patron by doing the following:
1. Go to People > Find a Person
2. Search for the person you need and click on the Reader's name
3. Select "Add Review" from top navigation
4. Enter the book's title, date, and review text
Alternatively, if someone demonstrates to you that they have already manually entered enough reviews to earn a review badge, you may want to instead go to the unearned badges tab on the left navigation and earn the apporpriate review badge by clicking on it.
