Daapleby has a point. To tell you the truth, I would never attempt to test someones software that is not from a reputable source. There are too many people out there looking to steal your stuff and you ID. i dont care if people say I'm being too cautious, and it wouldnt happen to me. Well, it has to happen to someone, so why not me?
Even with a spare machine, I wouldnt trust it. Like Daapleby said, nothing personal, but we have far too much to lose by someone taking control fo our computers. Like he also said, having a post that is no legible is not a way to get someone to test your software. That is the first signification that something fishy may be lurking abouts.
