I think you really need to define what you mean by user guide. If you're really referring to tutorials on how to do things in Poser, then there's no problem. Those are just your own little training guides and there are loads of those here and elsewhere. If, as Paul said above, you are just scanning text from the already published books, that would be a violation. I suppose, if you were to completely compose your own text with step-by-step instructions on how to use Poser, you could just refer to that as a detailed tutorial. It's a gray area, there. Check the tutorials here in Renderosity and see how they're written. If that's all you mean, then by all means, go ahead, as there are folks out there who will always need a good comprehensive and user friendly tutorial on how to do certain things. I think a complete how-to guide on the entire program might be a little risky. Then you might want to check with MC and get their blessings first. Melanie
