Why can't I rename a contact or provide something like an alternative description or nickname? With Trillian (and possibly GAIM - I haven't checked), it is possible to rename a contact. But with MSN, I can only see the ID (email address) and the name provided by the user. Sometimes neither of these is useful.
If I occasionally need to discuss something with Bob in Development, I have to remember that "Cameo" (foo123@example.com) is the one I need to double-click. Why can't I give it a label like "Bob"?
