How to disable the “Log in to iCloud” nag when logging in to computer lab workstations?

Every time a user logs in to a computer workstation running Mac OS 10.7, the “Log in to iCloud” nag screen appears….  How can I disable this?

Very simply, open the Mac OS X Terminal, and use this command:

defaults write com.apple.SetupAssistant DidSeeCloudSetup -bool TRUE

This will prevent the System Preference / iCloud preferences from opening for new users…
