You can't edit the *.list files, but you can dump the *.list files to text with 'listview', edit the text files, and replace the *.list files with the edited text files. If it were my site, I would write a script to: 1) Stop LISTSERV 2) Back up the *.list files 3) Run 'listview' against the *.list files to dump them to text 4) Run a regex against the text files to parse 'Owner' lines and remove any commas that are not immediately followed by an e-mail address. Or, alternately, any commas contained within parentheses. Or whatever other regex fits the format of the troublesome entries. 5) Replace the existing *.list files with the edited text files 6) Start LISTSERV LISTSERV will complain about the lists being in an invalid format, and then will convert them back to binary. I've used a similar method to batch edit thousands of lists in the past, and it works well. The hardest part would be finding the right regex, and even that isn't so hard, really. -- Liam Kelly Senior Consulting Analyst L-Soft international [log in to unmask] L-Soft offers a full range of Consulting services, delivered remotely or on-site.
