Harmen, For the Fractal Universe Calendar, Avalanche publishing specifically asks not to be contacted directly (that's why they have chosen Linda and me as editors for their fractal calendar). You can read about open submissions for other specific subjects here here: http://www.avalanchepub.com/2004/aboutus/submissions.htm It would be a terrible shame if your post led fractal artists to believe that images sent by individuals are being accepted in that category.
