I made one for my site as seen here:
http://www.apple.com/downloads/dashb...matioucom.html
It's really more photoshop and CSS than anything. A little javascript/html coding but nothing too drastic, Apple has a great tutorial site with some sample code that helps a bunch. I could make one for XS when I find some time next week (spring break). All I would need is some hi-res photos/gfx to work with. The only thing is that I only know how to get it to work with one feed. It sounds like you want it to handle two, the latest news and the latest forum posts. I might be able to fiddle around with it and get it to simultaneously display both feeds or have an option to select between feeds..
