We made sharing simple yet comprehensive by introducing four levels of "visiblity" which determine who will see your recipe. The visibility settings can be seen at the bottom of the recipe editor which is used whenever you create or edit a recipe.
It looks like this:
Everyone:
No restrictions. The recipe will be visible to the general public and will show up in web searches from search engines. (this is not available for "Private" users)
Only my friends and followers:
Only people who follow you can see this recipe. They will not show up on search engines.
Only my friends:
Only people you have hand selected as friends will see the recipe. They will not show up on search engines.
Only me:
Fully restricted. No one can see this recipe but you. They will not show up on search engines.
