[LM_NET] preventing teacher edition answers from xeroxing

[Adrienne Goldstein <arachgold2000@YAHOO.COM>]

Hi,
Years ago, I placed a certain colored transparency over a workbook page of a 
teacher's edition so that the worksheet answers didn't xerox.  I can't remember 
what type of transparency I used. Has anyone done this before?
