I'm sur FrogBoy will be along shortly to explain where we're at with regards to this alternate 'site'.
As I recall it was 'mooted' but hadn't formally been put into play.
Needless to say, the rights of the individual skinner/uploader will be protected and public notification/clarification will be forth-coming.
Please remember that Wincustomize.com and its crew are 'in the game' and in no way would they/we jeopardize their good standing with something at odds with proper protocol.
My guess is that the site 'got noticed' before it was due for airing...
