If you find that there is a person listed incorrectly in a department entry then:
1) Click on the person icon to see who are the editors. Send them an email.
2) If you are an editor then click on the pencil. This will take you to the Profile Editor.
You will now see in the Profile Editor a tab called "people". You might have "Display default Faculty/Staff list from Banner" turned on. If that is the case and there is a person listed that should not be then you either need to wait on the IT systems to sync up with Banner or have your college Banner person make sure the person was properly removed.
The second situation may be that you have create a group within the Group Manager that has a listing of these people. In that case you need to edit the group to change who appears.
