Bug - Call to undefined function Bullet()
I spotted this issue today. I posted a reply to a forum, and I got an error message about an undefined function called Bullet(). I checked file class.qna.plugin.php and, in fact, at line 294 there's a call to Bullet(), which isn't declared anywhere. Since there are no other calls to bullet anywhere else, I simply fixed this bug by commenting out the line, but I think it should be removed from the plugin itself.
