Keyword Violations
If you run the weekly keyword violations function you can browse the data typed by users that contains any of your configured keywords. As you can see from the example, the keyword iPhone was configured and captured during an email to my wife!
You can collect all such violations into an RTF file to display in Word, or an HTML file to load in your browser. Printing either might make for good reading over lunch with your senior management collegues. This is the ultimate ear on the grapevine!
