How is everyone proceeding with answers in comments? Do people normally ask the commentors to promote the comment, or is it best just to write a CW answer?
@AndrewSalmon [tag:calculus] creates calculus. By the way, I upvoted a few of your answers, but not all -- must be careful to not get hit by serial-voting script, which would undo the votes.
@AndrewSalmon Unanswered tab does not include questions with negative score. The sub-tab Questions:unanswered does. I find the Unanswered tab more useful, because it has different kinds of sorting.
