If you try to put the output of a REVIEW back to LISTSERV, you'll get an error. REVIEW doesn't send you the user options that are in columns to the right of column 80. LISTSERV recognizes the REVIEW format and rejects it. Now on the other hand, I suppose you could take the list header keywords section off of a review and PUT that (to change the keywords only)--but I wouldn't recommend it. GET and PUT are the way to do this. Nathan
