Many subscribers to CANCER-L who reply to a message routinely quote the entire message, which is sometimes multiple pages long, and add one or two lines of their own. This practice makes our digests much larger than they need to be and results in wasted space in our archives. Is it possible to configure LISTSERV to reject messages where the original content in the message is not N percent of the quoted text? I think the original content should be at least as large as the quoted text. Barry Wolman Pittsburgh, PA
