CASCADE maintains a log of activity for the documents that it manages. See section 5.5.1 for a description of the report generation component of this feature. Upon login the user is informed of the amount of activity since his/her last session. This activity could include people adding new documents or comments about existing documents. The user can choose to review a detailed list of this activity in order to find new documents/comments that the user is interested in. Some of the activities that CASCADE logs are comment creation, document creation, editing, and link deletion.
