Modding the Mac OS to suit your needs is common around these parts, but there is one area that often times overlooked. The Login Window. The usual way to modify something like this is to edit the .nib file that is called when logging in, but that is a separate story. If you know how to edit the NIB file it is located in
/System/Library/CoreServices/SecurityAgentPlugins/loginwindow.bundle/Contents/Resources/English.lproj. However, if you've never worked on a NIB before, there is an easier way after the jump.
