Is it time to invoke the
10 day rule?
According to the official
Rules for the Quiz Room (set down by Mister Underhill himself), section 3 states:
Whereas, "no new question has been asked following confirmation of a correct answer" [within 10 days], or
Whereas, "no response has been given by the question setter to the last answer" [within 10 days]:
Anyone may ask a new question on the topic.
(It should be noted as well, that "In addition, a thread may be considered stagnant if there has been no new post for 10 days or more")
