Vik, these webistes like gnome-look.org, kde-look.org etc are branches of http://opendesktop.org/
. You can even have pages for distros like Debian has http://debian-art.org/
. You can contact opendesktop.org and seek help in creating something like hamara-art.org. An alternative is to have something like this - http://cinnamon-spices.linuxmint.com/
but of course Cinnamon is a separate DE and we don't have one.
