Since modifying code is not allowed after an answer has been received, can a user comment on a question he/she just posted to state that the question is under construction, therefore postponing fast answers?
- User posts a question (it is on topic).
- After reading it again he/she realize something is missing/wrong.
- It might take a while to update the question.
- Posts a comment saying "Wait! my question is under construction"
Is such behavior allowed, or should the user delete and post it again?
