Maybe some new catagories?
I love your site, Chasms! I have used your site for years in telephone tech support. Having a step by step guide is invaluable on the phone to help people.
The forum is a good addition, maybe there should be a few other categories though.
May I suggest "Smart Phones", "Requests" (for if you are requesting certain screenshots or if others are asking for certain OS screenshots to be added)
