Registered users of Shopster will be able to submit their comments on the offers posted (apart from rating them). This way they will have the chance to express their opinions and say whether an offer is worthy for example, or maybe say if there is a catch for obtaining a specific offer, or even give some details about the technical specificiations of a product. However, these comments should also have some kind of evaluation and undergo criticism from the rest of the users reading them. Therefore, we have decided to include a rating for every comment and other users will be able to say if that comment is helpful or not. These ratings will then be weighted and will reflect to the user’s overall rating. So if for example a user’s overall rating is quite low and a new Shopster user sees a comment from that user, he/she will know that the specific user is not very trustworthy and that the comment is probably not accurate.
