I have almost no use for a cad program but if I did, I'd want to see what it is before I give my e-mail address to what will most likely turn out to be a spam marketing company. There are absolutely no details about this cad program on their site and it makes me think that most likely you'll be downloading some POS, useless software program while they'll be patting each other on the back for getting 100,000 idiots interested in cad programs for their newest e-mail list.
