Flagging posts to be viewed only by admins or mod

Toggling a regular post to a whisper could only work if the email for it hasn’t gone out yet. Discussion:

Unable to retroactively make a post reply into a whisper

Er, the cat is out of the bag once you post as a not-whisper. Going back and retconning posts into whispers via editing is not something I can support as a feature.
