I quite often encounter questions with at least one vote to close (VTC), but no comment or down vote. This means the OP doesn't know there is anything wrong with the question.
Would it be possible for the first VTC* to post a community comment with the selected vote to close reason. Allowing the OP to be notified there is a VTC?
*I think there would be a benefit to having this happen for first time askers, even if the user has the View Close Votes privilege, which is gained at 250 rep.
