I have brought content modules in the market that added to the outline but not the spy, and some that don't add to either one. All content modules should add to both the spy notifications and the outline. Those two are very important when it comes to interactions. I have a content module; by content module I mean a module that adds some form of content, text, photos, etc., that does not add to the spy or outline and that content gets almost no response from members. From now on, I am making that a requirement of any content module before I pay out my money. What good is it to have added content if it stays burred on the site and no one comments on it? Notices, it is all about notices.
