What does "Fame: xx/yy" on the left side of forum posts mean?
You earn Fame points in the site in two ways: 1) by getting repped (via the + Rep button) by other members; 2) by contributing content, like hosting a Challenge or Tournament, or by uploading a Tutorial Video. The numbers shown on the left side of forum posts represent each member's values for those two types of Fame - the first shows reps, the second shows contributor points.
