Users can “Vote” on any topic in the forums. Voting up gives the topic (and the user who created the topic) a point; voting down removes a point.
The “Points” value is the sum total of votes received. Users’ points are the sum total of all the points for every topic they’ve started.
What Are Points For?
Every forum is a collected list of topics started by the community. The topics are all displayed in the order in which they are posted. However, the “Sort topics by votes” button allows you to organize the topics by most popular. The more points the topic receives, the higher its placement in the forum.
