I sure hope this guy isn't a troll about to use these questions to try to make money off our work with no attribution: http://groups.google.com/group/Making-your-Website-Sell/browse_thread/thread/badbf6cf41c1539d/2e532ebe84c3e03f#2e532ebe84c3e03f
How about it Phper? Is that what you are doing? You will get extreme flamage from me if that is what this is all about. We've seen several of those "blogs" where people just rip off other people's work for the purpose of click income (or even ripoffs for book income), and it is plain reprehensible, and often illegal.
That is something that might go in the minifaq. Just thinking about it, I'm getting steamed.
