Commenting isn't anything new in poser files, but I think the main reason it isn't used is quite simply that the average user would never in his/her wildest dreams, think of going hunting through a cr2 for information like that. If it were done by everybody, it would be more widely known. As it is, I can't think of a more obscure place to put useful information. Xena's method is the most noticable. The minute you go near the materials, you can't help but see it. mac
