I am trying to udnerstand the rating system. There are two options as far as I can see:

1. Using the stars to assign a rating and controllable via settings of GPS Tools. 
2. Using thumbs up or down. How to show or hide this and make it available I can not find. On the GPS tools demo site it is nog working as well. Only option I currently have to use it is to log in as a super user. Access rights settings  seem to have no influence. Is it possible to enable this for users and if yes, H2?
