Yes, I agree Judy. I also thought the same as Jesskimo until I did some reading online about what constitutes someone's 'own' recipe.
Apparently you can't 'own' a set of ingredients and or method. When we convert things to be TMX friendly, there is a significant change in the method with most (if not all) recipes so that seems to constitute enough of a modification -IMO.
However just to be sure I always say who/what I was inspired by with links where possible, that way people should be happy for others to share their ideas as it generates more traffic to the original site/reference.
I do recall some correspondence with Dan Lepard's communication person regarding copyright of recipes here on the forum. That's what got me reading about it in more detail. I read all the relevant blog postings and links, made for an interesting afternoon of reading!
However I know there are others on the forum who have much more knowledge in this area than I do.
