Betty_Kelly After opening my email today and seeing 31 notification messages, I got fed up too and figured out how to disable them. At the top where your profile pic is, click the gear symbol at the end, select Edit Profile, find Notification Preferences in the menu that opens, and uncheck the second to last box "Notify me when people comment on discussions I've participated in." I don't know what "Popup" is, but I unchecked both that and "Email" just for the hell of it.
