I recently asked a question on Math.SE that hasn't received answers. I plan to do some major edits to it, after which maybe someone will be able to answer it. In the mean time, I don't want new posts added to the question, because they won't fit when I am done editing the question (which can be a couple of days from now). Can I somehow freeze the question?
For now I'll delete it, and later undelete it. Is this appropriate?
