I have a client that wants to set discounts by category for Black Friday, 11/29/2013 00:01 to 12/01/2013 00:01.

Setting it up is pretty easy EXCEPT, there is no explanation in the online documentation that I can find for "Number of times used" and "Quota". If we leave it blank, is it basically considered as unlimited or do you have to put in a high figure such as '999999999' to ensure the max is never met? Yes, I know, common sense dictates that if there is no value in the field, then it is considered as 'unlimited'. But I didn't write the code and I want to be sure exactly what you're suppose to do with those fields if you want them unlimited. Frankly, you need a hover tooltip that explains that.
