It's starting to bug me that an increasing amount of people think it appropriate to flag their posts with the stupid flashing red exclamation mark. Usually, it's a post that does not warrant such an icon. It's an unwelcome distraction on the front page, and the icon itself has terrible aliasing anyway. That said, I don't seem to have it as an option to select when creating posts. Is it actually an icon that only some of us have, or is it some kind of error placeholder for a broken icon?
