This option is available if you use MSN Messenger 7 in combination with Messenger Plus! 3.40. For more information, see
Preview of improved Custom Names feature in Plus! 3.40.
Note that both of those programs are still beta releases, and you are not supposed to use MSN Messenger 7 unless you're an official MSN Messenger beta tester. Using beta software means that the programs might contain bugs, and using MSN Messenger 7 is also illegal if you're not an official beta tester. It is recommended to use the stable MSN Messenger 6.2 and wait until MSN Messenger 7 gets officially released (might be no sooner than February 2005).
