Logon Information
The project page can provide users with general logon information. Such information includes who is currently on the system, how many times a user has logged on, when is the last time the user visited the site, etc.
This information can be useful because members of the team can monitor the use of the site. For example, if a subcontractor habitually neglects to review the weekly schedule update and then creates a delay in the project, the site automatically documents it. This could support an argument should any of the parties on the project enter into litigation.
