Dear all, following feedback from some of my customers, one of whom described my anti piracy and security measures as "better than the Pentagon's" I have seriously rethought the security of the kits and I am grateful for everyones input. I have no choice but to protect the files on my web server against leach downloads in some way, since this is how I serve the kits out. Wings Of Horus is a commercial venture, piracy is a serious issue for me. I have however taken on board peoples comments and I agree that I need to reconsider my position. I think I have been concerned by discussions on cardmodels.net and other forums about the piracy issue and missed the point about why I design in the first place. I'd appreciate your opinion on this compromise. I have altered the system so that a customer needs enter a password only once to decompress and extract the password free model to their hard drive to a "My Models" folder, or other location. My email delivery system can deliver a password key, and I have re-written the sales notices to make the process less daunting and more straight forward. Thank you for reminding me that I should, after all, assume that the vast majority of folks willing to part with hard earned cash to obtain digital kits, are honest and want nothing more than to build a model subject that interests them. As such I should grant them more trust. As a gesture of good will I shall be delighted to recompile kits for existing customers and send you a password free file on request. As always your views and input are valuable to me as I venture into e-commerce and experience a steep learning curve.
