Points Log on your Public Profile
I may have noticed this since it’s been active for a few days. On your public profile you have a log of the points you’ve earned on this site. What’s nice is there is pagination as well. So you can review your history all the way to the beginning if you wanted to. In fact you can view anyone’s points log now.
There is also a Sitewide Points log available on profiles that show the points earned sitewide. But it only shows the last 20 logs at the moment.
To access it you log in and go to My Account > Points > My Points or Sitewide Points. Or just visit any profile and click on the Points link.
