Tagnatures don't exist, I've never even heard that term used before in my life on the interest (5+ years) I've only started my true forum experience about half a year ago, but I know well enough that it's always been "signature" and as one of the people had said, no matter what, it's still a signature. And obviously it is some idiotic person just trying to be cool, in essence, I bet there "tagnature" sucks?
