These pages are only accessible if you have privileges as a site administrator. There are different screens:
When you enter the site administration area you will get a status page showing you
the total number of issues in the database
the total number of projects in the database
the number of active and deactivated users
the number and names of users that are currently logged in
You may change the operational mode of the Track+ installation from "Running" to "Maintenance". This will prevent new users from logging in, giving them an appropriate message. This way you may take down Track+ in a controlled way for maintenance. The site administrator may always login.
You may deactivate and reactivate users in the Track+ database. Since now history should get lost, users cannot be permanently deleted from the database, but they can be deactivated. Deactivated users do not appear any more in most user related select boxes. They will not be notified any more of any changes either and they cannot login. When a deactivated user tries to login she get's a message that her account has been deactivated and that she should see the site administrator to get it reactivated.
You may add, modify and delete the departments list.
