This patch allows you to enter display names of several lines. Mind you, these don't show up as such in the contact list, but in the conversation window and sign-in alerts.
Instructions: Close down MSN Messenger 6 completely. Unzip it into the MSN Messenger directory (usually c:\program files\msn messenger\), run and apply the patch!
