Massachusetts Institute of Technology freundlichen Gruessen (the last greeting of a letter needs to be printed)

(Print it out and sign a KevinZKF in this position.)

This is a more formal practice, usually by signing official documents or letters. The document may not need to be greeted, but it is the same when signing. Print it out first, then sign it to show approval, not misappropriation.
