Great looking pizza once again Norma! I understand that you can't share the secret recipe, and it's good that you're honoring your word!
That said, I've never understood the point of keeping recipes a secret... even in a competitive situation, making money is more about running a business than it is about having the best food. Just comparing Pizza Hut to your local mom n' pop will tell you that! Not to mention that with enough time, money, and effort, it's possible to reverse-engineer just about anything in the world anyhow! These folks sitting on "secret recipes" are pretty silly if you ask me! 
CDNpielover,
Maybe I am missing your point, but if I had a great dough recipe of my own creation, and I had a pizza business whose success depended on that recipe, the last thing I would do would be to reveal it. I would most likely protect it as a trade secret since copyright law usually provides little legal protection for recipes, and filing for patent rights and perhaps having to enforce them later are very expensive propositions for the small pizza operator. Suppose, also, that I was a lousy businessman. If I were to reveal my dough recipe, someone who is a much better businessperson than I, or someone with significantly greater capital and perhaps able to sustain a period of predatory pricing, could set up business across the street and put me out of business--using my own recipe. Individual pizza operator or big pizza chain, they both take--or should take--prudent steps to protect their recipes. People don't put their time and energies, and maybe even their life's savings, into something and then give it away so that others can use the fruits of their labors without compensation. That might happen here with members of our forum who share their recipes with the world at large, but it doesn't work that way in the real world.
Norma is doing the right thing. And it shouldn't matter whether the person who disclosed the dough recipe to her is a nonprofessional member of this forum or an employee of a major pizza chain. The person who gave Norma the recipe was trying to help her out of friendship and kindness and maybe to help her in her work at market, not to put the recipe into the public domain. Those in the public domain are free to spend their own time and their own money to try to reverse engineer and clone someone else's recipes.
