While 3D-PRO is not a software or technical support group, posting to the list is sometimes the quickest and easiest way to get an informed response due to the combined knowledge of the group and the enthusiasm of members who are happy to share their knowledge.
3D-PRO members include a number of people who helped write the book (or the format, the renderer, the plugin, the process, or the article) on board.
As long as these types of posts do not become disruptive — and folks make an effort to search for answers in more appropriate places first (I.e. manual, software support forums, etc) — then software (hardware, etc) support and technical questions are welcome.
If you are posting with regard to a specific piece of software, please use an appropriate subject header key.
