Are you talking about the "itunes" skin? If so, don't worry, it is not lost
It's just that the incoming ftp is not checked very regularly, and with the 0.7.2 release everyone has been very busy. But your skin will be on the website (http://www.videolan.org/vlc/download-skins.html) in a few days.
About the skins2 documentation: it is now written, and available in the VLC source tree. It should be on the website within a few days (hours?).
Please consider using skins2 for new skins, as the old skins module is going to disappear...
