Wow! So fast! Thanks for taking care of this!

Did we think we would need the Rubric types for anything scoring related down the road? In other words, will each widget need a Rubric when our new scoring is set up? Maybe we don't know the answer to this yet, and I suppose we can always add these back after we get a better picture of how the widgets are set up. Wait, I think the point is that these won't need to be scored, so, carry on!
