Why is rating functionality limited to Level 2 users and up?
This article describes why we limit the rating feature to Level 2 Answers users and up.
Ratings are a powerful way for you to voice your opinion on the content of Answers, and determine the direction of the product. By waiting until you reach Level 2 to exercise this privilege, we encourage participation while discouraging the abuse of this privilege.
New users to Yahoo! Answers start with five questions a day so they can learn more about using this service before being unlimited in the number of questions they can ask. If you'd like to ask more questions each day, answer other questions and vote for best answers to get to the next level. Check out our Points and Levels page for more detail.
