Remove Subtitle on Login Menu

Question

On my login menu there is a line of text right below "OS X" and the date/time. This may have been added by a customization app (cocktail, tinkertool, etc.) or by a terminal command. Whatever the case, I want to remove the text but I can't figure out how.
Any help is appreciated,
Mitch

This, from the Tiger Server Security Configuration Manual, should get you started:
*+Chapter 3 Protecting Hardware and Securing Global System Settings 59+*
*+Setting a Local Login Warning Banner+*
+You can configure your computer to display a login warning banner when a local user+
+logs on.+
+To provide a login warning banner to any local users:+
+1. Convert the binary property list com.apple.loginwindow.plist to an XML file using the+
+following command:+
*+$ sudo plutil -convert xml1 /Library/Preferences/com.apple.loginwindow.plist+*
+2. Open the file /Library/Preferences/com.apple.loginwindow.plist as an administrator+
+using a plain text editor:+
*+$ sudo vi /Library/Preferences/com.apple.loginwindow.plist+*
+3. Immediately after the <dict> tag, add new lines with a <key> and <string> entry, as+
+shown in bold in the following command. The new <key> tag must contain+
+LoginwindowText, but the new <string> can contain whatever warning banner has+
+been indicated by site policy.+
+<?xml version="1.0" encoding="UTF-8"?>+
+<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://+
www.apple.com/DTDs/PropertyList-1.0.dtd">
+<plist version="1.0">+
<dict>
<key>LoginwindowText</key>
+<string>Your text goes here+
</string>
+4. Save changes and exit.+
+5. Convert com.apple.loginwindow.plist XML back to a binary property list using the+
+following command:+
*+$ sudo plutil -convert binary1 /Library/Preferences/com.apple.loginwindow.plist+ +*
+The warning banner should appear for the next person logging in to the computer.+
Alternatively, you might be able to do it with:
*sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText "your text goes here"*
I haven't tried that, so proceed at your own risk.
