Hey Katie,
I just found out that a girl named Aqua stole your header. Her site is http://www.aqua-graphics.de.gg and it's a german site. She put her copyright to your main-header (look at this picture: http://www.myimg.de/?img=sigi39f84b.png) and told her visitors it was a selfmade signature.
You can see it on her site it you click on "Signaturen", if you don't find it, visit this link: http://www.oyla.de/cgi-bin/eigenes.cgi?page=text&id=863314721235747006&userid=89577644 and look.
People,please tell Katie if someone steals her graphics or like this.Thanks.
Chiara-Wusel
