George,
As Howard said this is an old post. There is however a eSafety course in Moodle.net that was written for a high school that might give you a place to begin. You can download it and restore it to your own site and then edit to meet your needs or begin your own. You can set up your site so that people can get an account fairly easily and then you will have records of who completed your course, "signed" user agreements, etc. One thing I would add is choice activity where students or employees accept the agreements as a matter of record.
