Quick Rubric is the wonderful new (beta) site for creating rubrics from the creators of Storyboard That. This is far and away the easiest site I've seen for creating a beautiful rubric where a user can add a row or a column with a tap of an arrow button. Everything inside of the rubric is customizable (i.e., from the heading to customizing points) and a user can save or print out as many rubrics as they need.
I highly recommend checking out Quick Rubric by clicking here.
