Signature introduction...

You have to love GingerOfTheNorth’s: ‘I don’t think so, so I’m probably not’. That is pure genius. Where do these guys come from?

Huh? Are you asking where Ginger got her particular sig, or how to append a sig to your own posts?

It sounded more like a direct question asking where all of the posters come from.
This would be a poll, so a thread in IMHO is the right way to go.

Sounds to me like the Net is asking, “Where do great sigs come from?”
