It's a new feature in myBulletinBoard. In myBulletinBoard, you can rate posts to give members a reputation. Reputations will be shown as red or green squares, and depending on the number of positive ratings, one or multiple red or green squares will be shown.
However, WDZ (this forum's administrator) hasn't had time to set it all up: i.e. should we rate members or posts, who should be able to rate members, can ratings be changed or withdrawn etc.
Now everybody is still neutral and the reputation system cannot be used, though WDZ said he was going to post polls to find out everyone's opinion and then he'd set it up
