I was helped greatly last time I posted a question. I've developed a screen saver program that generates graphics and I'm planning on attempting to market it but I need a registration code system for it. I plan on offering a version that someone can download for free so they can view the screen saver and then after a time there would be an annoying message that you could eliminate by registering the screen saver for a fee. Does anyone have a recommendation for where I should look? I'm sure I could create the necessary code myself but I could probably save myself some time and have something that's more secure if I use something that's been professionally developed for this purpose. Did I use enough smiley faces?
