Abstract: Often it is desirable to present content (e.g., documents, websites, etc.) in a conference or meeting. Presenters may encounter relevant content at various times prior to the conference. Tracking content to be used in a presentation (e.g., conference, meeting, journal, etc.) is more easily facilitated by allowing a user to tag content and thereby associate the content with a conference. For example, a user may drag-and-drop a webpage to a calendar event associated with a conference or vice versa. When the conference occurs, the documents are presented or made available to the conference participants without requiring additional human action.
