Adding / Removing / Changing Flags
Fragment of a discussion from Science talk:MER/Flags
So in the current system, newly created pages have pre-written flags (CQ, CH, CS and CT) at the mother level (.../Question 1). It is true that flags could be added at the child level (.../Question/Statement) but it makes life much harder for everybody and creates a lot of duplicates. So the recommendation is to keep flags at the question page level and not at any of its child.
Hope that's clear enough.
It happens that I changed the flag instruction exactly as how you reply. I did not intend to suggest a change for now. Just as a placeholder for future thoughts. And if new contributor got confused he/she will understand what's happening by reading this discussion.
