YOU can give YOUR permission to be listed on YOUR contact's friend list, so that the CONTACT of your CONTACT can see YOU on the friend list of YOUR contact.
It is done via Windows Live Spaces.
Note 1: Before you can add someone to YOUR Friends list, you must have a profile on your Windows Live Space.
Note 2: YOUR space permissions determine who can view YOUR Friends list.
Note 3: Other people MUST give THEIR permission to appear on YOUR Friends list.

PS: very important: for everybody: If you do not want your MSN email known to 3rd parties, clear your entire friends list and do not use it. There is something very dodgy with the list where if you add someone to your list, you automatically will be added to their list. And thus you actually will not have control anymore as to who can see your MSN email or not.... So, if you do not want your email known, clear your friend list completely and do not accept requests to be added...
