I was looking through a book titled _Digital Camera Solutions_ and right in Chapter One, p.28, first there's: " FInally, if you have an appetite for yet more information, visit the Photonut site, http://www.photonut.com, where you'll find lots of links and real-time chat. If you are prone to sign up for mailing lists, try Photoforum..." Right below Photonut....hmmm....no biological analogues, please.... --- Luis
