No easy way to do this except parse the LOG file.

We've done some work on this.  A somewhat backlevel version of our
program for producing stats from the LISTSERV log is at

   Host:       ftp.cu.nih.gov
   Userid:     anonymous
   Password:   guest
   Directory:  raf
   Filenames:  lsvstats.zip (binary) or lsvstats.uue (text, uuencoded)

Use an FTP client, not a web browser.

We haven't updated the distribution in a while.
