Karl-- Our Listserv guru, Chuck Kesler, designed a program that keeps track of GET requests--since the only thing we mail out automatically is the table of contents, everything else that anyone reads is retrieved via GET (or via anonymous ftp--but so far, I don't think that many of our subscribers are getting things that way; that guess is based on the number of requests for info about ftp--the program which tracks GET requests does not track ftp).
