Glenn,

Thanks for the reply. I was just using that as an example. Of course, since they are within our mail system, there would be no problem. However, if I am the MarCom company trying to reach those people, the sales manager's boss could end up with two or three of the same email and the MarCom would not know it.

btw, on of your other responses pointed to the wolfram site. I had heard of mathamatica and we used it in gene research, but I had not heard of the web site. So I got two great things out of you post.

Nick
