Dave Haupt contact details?

A few years before he disappeared, he offered all his modules for free on his site. I believe that he had a specialized module key that was just like the normal module key that you normally would put the serial numbers into. Most of his site's history is available on WebArchive, I believe. Here is a link to his module key:

I believe that you just throw it into the container of the modules you want registered (that's how it works on mine, but I have the old version for the modules I purchased from him, so I don't know if it's any different.)

Good luck!
