The text is ok, but the link still points to the old Danica site. I think you need to re-edit your signature and use the "hyperlink" icon which allows you to paste in the new url in a dialog box.
Currently it shows up like this in the page source:
<a href="http://www.danica.com/flytier" target="_blank">http://www.f</a>lytierspage.com<br />
