"Along with the "Follow" buttons, there is a Bookmark button for individual forum discussions. You cannot bookmark a Community, or an Inbox entry, or a person. As we said earlier, your Jive Bookmarks are managed from the Spotlight Search tool. You can set a bookmark as "private", but if not your name will show on the right sidebar so everyone else can see you've expressed an interest in that item."
-- What, and where is the "Spotlight Search Tool?" -- It isn't mentioned anywhere else in the User Manual.
