I do somewhat agree on the risk part, however many one man shows have seen lots of success, and for most of us that is how we start out as I did. Programming can be isolated and lonely. It has become my policy, and I believe it should be of everyone else that you should not buy or even try software from someplace you cannot verify, or somehow conclude that the product has potential to serve well, which I believe it does. Do I know there might be some kind of trap or back door, well the answer is no. For what I have seen the developer has demonstrated good intent here and wish him the best, and as they say here in Canada the law always gets their man if there is any wrong doing. The only risk that I see is if I try to make something out of something that is not possible and that is why I am doing due diligence for this product as I try to learn what are the limitations as this is quite new to me.
If it was a compiled application or eCommerce store I would totally stay away from any site without a phone number and address that I could not verify. There are too many scams out there. Which sadly I have fallen victim to. In this case I am going on more than a gut feeling which the news groups seems to support, but then again I could be wrong. We all have to take risks at some time and I am willing to gamble on this product for basic projects for now.
