Why are you guys even bothering? There are tons of free CAD programs out there right now. This bull$hit offer doesn't even have any information about the software everybody is clamoring to get.
This is obviously not a legitimate company: "We'll give away our product for free, but only if enough people sign up to make it worthwhile" doesn't make any sense. Let me tell you what's going to happen... The scam will run and run until the perpetuator collects X number of addresses. Then, the web-site will disappear and nobody will ever hear another word about it. Meanwhile, the list of 100,000 names of people who are interested in new CAD software will be sold to a company who makes such software. Their marketing department takes it from there.
It's stupid, don't contribute to these tactics and make yourself vulnerable. If you're interested in CAD/CAM programs do a little research and choose from the dozens of options out there with free demos or unrestricted personal use licences.
