Member Points are an index of your participation in the more social or community-oriented aspects of Chess.com.
You get a point every time you...
- comment on something
- create a forum post
- post a blog
- publish an article
These points show on your homepage. You can't do anything with them, they just show if you're an active poster on the site.
I still don't know about the rules and payout processes of this forum. What is the minimum payout? and can't we earn while someone replies in my post?
