...If you DON'T register your car every year you CAN'T legally drive it. If you DON'T register Poser5 each time you put it on your machine you CAN'T use it. There are two glaring aspects that nullify this as an argument. 1. Car registration is imposed not by the manufacturer but by the government. It is a related but entirely separate matter. 2. The proceeds from car registration are theoretically used to benefit the public by providing funds to maintain roadways, etc, etc. While the benefit to CL is obvious the benefit to its' public is less clear. And please don't tell me that it is necessary if I want Poser to survive as a product so I may continue to use it. Software is like life on earth. Something will always come along to fill an ecological niche and if it's not Poser it will be something else. I don't mind entering serial numbers when installing software. I don't even mind registering if it is a one time process. But I have been subjected to similar protection schemes in the past and it has always proven to be a PITA! So put me in the category who will not buy P5 with such a protection system active. While I cannot avoid all inconveniences or inequities in life I will avoid those I can. It happens that P5 is eminently avoidable. - Jack
