I think that persons that put up the freestuff don't want renderosity dictating what usage rights are to be put on their stuff. I also think that whining because we downloaded something for free, and then finding we can't use it in commercial renders is a bit of an outrage. It is hard enough to render a good thumbnail in poser (I just hate the convulusions) without having to put other stuff on them. I posted two free photo-real highres textures for the daz briefcase recently.. with 600 plus folks downloading it, fot two nice comments and one bitch because it was a big file. My point is, if you want folks to continue to post freestuff, don't make it so hectic to do so that they start to hate the process.
