19 February 2002 - primitive Earth beings

Greetings, primitive Earth beings. I have journeyed between the stars to bring to you the fruits of my own advanced civilization, that your planet may be released from its present dark age. On this CD-ROM I have recorded the details of an invention which, my models predict, will profoundly invigorate your nascent culture, from the lowliest prime minister to the greatest office clerk, as it so recently did my own. Earthlings, please accept my gift, the first 100% effective spam filter.
