Unbelievable!
How do I get "Points"?

To get points, you comment on something, create content (thread, group, tourney, etc.), in either the main site or a group.

Member Points: Chess.com keeps track of all of your contributions to the site such as comments, blog posts, forum participation, articles, etc. Each contribution counts for points. This helps members know how involved each other are in Chess.com!
