What do You Consider the "Core Sites" Of the Community?
Over the years, skinning has waxed and waned in popularity. Sites have sprung up, risen high, crashed and then been reborn from the ashes over the 10+ year history of Windows skinning. WinCustomize grew out of the fall of Skinz.org back in 2001. DeviantArt started as a skinning site but has turned into a digital media giant.
Of the skinning sites still around, which do you feel make up the core of the community now? What are the sites you visit on a daily basis to get the widest selection of skins, wallpapers and icons?
