To be able to see the new attributes in the Tracker, you need to update your Filetype database. Do this by running BeOS -> Preferences -> File Types, selecting application/Person and adding two extra attributes:
Attribute name: "IM Connections", Internal name: "IM:connections", Attribute type: "String", Editable, Visible, not Extra, Display width: 80 and Display alignment: Left.
Attribute name: "IM Status", Internal name: "IM:status", Attribute type: "String", not Editable, Visible, not Extra, Display width: 80 and Display alignment: Left.
