I agree that there needs to be a line drawn somewhere. I don't think 2 versions behind is all that much. When Poser comes out with a newer version 7, then they should offer incentives and huge discounts so that people can at least upgrade to the next version up from theirs, so that way support continues for Versions 5 to 7 inclusive.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
