Hello Simon Kwek,
One of the preferred methods is by using one of Messenger Plus! Live's
features. You can obtain a copy from here:
http://msgpluslive.net/download/
Once installed, open your contact list (make sure the menu bar is
showing or click the little arrow inside a box that is to the left of
the minimize button) and select the "Plus!" menu, then click on
"Preferences..." in the sub menu. Now that the Messenger Plus! Live
Preferences window is active, select the "Messenger" tab along the top
of the window and make sure the "Allow me to connect to several accounts
simultaneously" is checked to enable the polygamy feature.
To open up another instance of Windows Live Messenger just double click
the icon on the desktop or launch it from the start menu.
