In all the weekly newsletters I receive, there are usually 2-3 questions in the "Greatest hits from previous weeks" section, and 3 in "Can you answer these questions". Today's ELU newsletter has 6 in the previous weeks, and there's no "Can you answer" section at all.
Is this a bug, or does it increase the previous weeks limit if it can't find any questions for the last section?
I just got my ServerFault newsletter, and see the same thing. 7 questions from previous weeks, no "Can you answer".
