3Dworld had poser on the front cover a while back and like most mags has circulation figures on the inside cover. Latest issue of 3d world has a circulation figure of 14,521, down 6,000ish from the issue which had poser on the cover. Computer Arts (greater circ than 3Dworld) had an issue also with poser on the front, unfortunately those mags are on the bookshelf and more than an armsreach away :) Other Mags I believe which gave away poser were PCformat and another games style mag, cant remember which :( Not sure if Digit has done a Poser issue as I dont get Digit on a regular basis.
