Warning System Notification

[RocketFoot]

Do you guys know of any way to create a public notification when a post is warned by a mod?  Ideally, I would like to display a red box in the postbit after a warn is issued.  The logic is so other mods do not hit the same post again with a warning.  I hope someone can help as I have a fast moving board and some volatile debates!  I need something quick!
