Attachment removal.

Hello, Here is the first of many questions I have about smartlist. Is there a way to make the digest go out without being an attachment? I have several members that are complaining about it. BTW I am not new to running a list. The 15th of this month I'll go in to my third year but that is done without a server. I have 920+ subscribers on that list and am well aware of all the gripes and groans sent in because of someone jerk not liking this or that. I would like to loose the attachment though. Help would be appreciated. Cheers David
