GrumpyMonkey, There is no such option in my version of Evernote. (Dec 2015). This is exactly precisely why apps need to stop changing their user interface every six months. There is also NO reason this should be this difficult. There should be an option to stop sharing notebook right off the right-click menu. No excuse for it to be this difficult. There is no X ANYWHERE next to people's names. I can change permissions and no permission is NOT on the list. I am left without a way to do this. And Evernote wants me to pay a subscription for this. Problems like this are making it much less likely this will happen.
