Since the question was posed about copyright related to recipes we did a bit of checking to find out what the actual law is. You can read the US Copyright Office full document here: http://www.copyright.gov/fls/fl122.pdf
Basically what we understand from it is that you can list the ingredients of a recipe but you must word the directions yourself. So please post recipes accordingly. Please do not cut and paste a complete recipe with it's directions without getting permission to reproduce from the copyright owner and placing that in your post.
Thanks so much and I hope this doesn't deter you from recipe sharing.
