The D list is good for persons who have a restriction on the number of emails they can recieve. Otherwise I think the L list is better, because you can quickly delete those that don't interest you and print out or reply to the ones that do, without all the clutter of the D list. If you belong to the D list, be sure when replying to cut out everything that does not relate to your reply. L list is much easier. "THANKS SO MUCH FOR YOUR INFORMATION.
