Once on a product description page the visitor of your ecommerce website can leave a product review. He just will have to click on the "reviews" link at the bottom of the page or in the "reviews box".

The user doesn't have to be registered on your website to use that feature but you will have to "approve" each review to allow it to be displayed on your ecommerce website. (see 2.)

The user leaves the details such as firstname, surname, comments and a note.
Once the review finished the visitor click on "continue" and he is notified that his review will be displayed only after been approved.
