FYI, I'm working on a prototype to add "on click" popovers to each badge in the grid which will explain the badge and eventually inform members what they need to do to be awarded this badge. For example, if you have 800 posts, the badge awarded at 1K Posts will inform everyone that the member needs 200 more posts to be awarded this badge. Still working things out... maybe a few days or so before I get it working in beta.
Coming soon!
