A standard question-mark smiley for content annotation.
I'm constantly wishing there was a question mark smiley available. It would be most useful to set off comments/questions about the existing content, or to mark statements that you aren't too sure about. I would suggest three versions of the icon, one with an arrow pointing left, one pointing right, and one that's just a question mark. This allows you to point in the direction of the questionable content (or even surround it).
Suggested Markup
<?) : question mark pointing left
(?> : question mark pointing right
<?> : question mark (not pointing)
Suggested Graphic
Graphic design is not my strong point, but I threw this together in PaintBrush as an example... 
The important thing is that it is visible on a variety of background colors, and it stands out.

Discussion
I was just looking for this! I'd love to see it added. I'd use it to annotate "action item" lists (along with 
), as well as question/answer dialogs in design discussion pages, etc. Hope this makes it in. If general info exists on how to add smileys to a moinmoin installation, perhaps a link should be included here 
Implementation
For Moin 1.6 you can now use ThemeMarket/MoinDroplineIconSet, which has also a built-in question mark smiley -- OliverSiemoneit 2007-01-01 22:20:23
