Hi Simon,
You could add a shiny favorite icon (the one which is displayed in front of the URL) for your PN2 web site using the following HTML:
<head>
<link rel="shortcut icon" href="/xxxxxx.ico" type="image/vnd.microsoft.icon">
...
</head>
Then you have to provide an .ico file (name it anything you like). Size of the icon is 16x16. The one with which you use to compile PN2 should do the work.
Finally, you just need to put this line in every web page.
Hope your website getting better :)
