having now reached three figures 100 points, I wonder what contributes

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!

so they don't do anything for you but people notice how active you are

They are just a guide to how active people are on the forums and blogs.

thanks for the info', does anyone know how many points are allocated for each of the various things ...

 Well, a forum post (like this one lol) is worth ONE point.

Endless Quiz question = zero points

If you post a photo album or a blog, I think it is 5 points!

thanks chessbot7

for some reason I'm scared to open up much in identity terms photos etc on the net, maybe in time.

waa

thanks for the open outlook Rocky, I lack your confidence.
