I need to buy a software for grammar checking and proof reading for someone. He insists on http://www.whitesmoke.com/ He has worked with it and likes it the most. My Firefox WOT plugin goes full red when I go to their site and I have read bad things about them. However it seems they have a valid VeriSign certificate and my Norton toolbar also says its secure. I did a search and found another alternative http://www.gingersoftware.com/ my WOT stays green with them and I have not read bad things about them. If I buy the Ginger, it's twice expensive as Whitesmoke. What do you suggest? Is it safe that I buy from the whitesmoke site? That's what he wants but if it's not safe I will try another.
