The first time you log into a new account with Mountain Lion, a special iCloud login screen is shown. Once you "skip" this screen it is never shown again.
When setting up an account I like to add a few things (like a welcome note of my own). But I'd also like to leave the iCloud login screen intact for the first time the intended user logs in.
Is there any way to reset this login screen so that it will be presented on the next attempt to login to a given account?
