If you ask a question that you know should be CW, should you flag for a moderator immediately after asking?
Remind me again why you removed the option for authors to mark new questions as CW.
Chances are the question is not appropriate, consider not asking it, or rephrasing it until you no longer know it should be CW
Because it was confusing, and also people used it as an excuse to ask questions not quite appropriate
That said, If you really need to ask it, flag it for mod attention and ask for it to be converted.
