This issue was discussed some time ago on the Woodstock Talk page; please go there and review the commentary if you're interested.
The site www.woodstock.com may appear to be an "official site" of the old/new Woodstock festival(s), but it's nothing of the sort. At the bottom of the main page, it says: "Woodstock.com is a community for artists and fans to share their experiences from all concerts, including the Woodstock Festivals." Nothing "official" about this site at all; it falls just short of misrepresentation, and rather cleverly, I might add. Thus, this site was long ago identified (after brief discussion) as linkspam by regular editors of the Woodstock page.
