hey soul,
in case you are interested, i have thrown together a simple little favicon for fos based on the old fos crosshair logo. if you want to use it, feel free, if not, thats cool.
if you do use it, all you have to do is name it favicon.ico and place it in the root dir of the website and most browsers will pick it up and display it in the address bar and tabs.
