I'd like to add to Jim's advice. As I understand it, the procedure he described will enable him to authorize someone else to update certain files that already exist, but would not enable them to create new files. That can only be done by altering the FILELIST, and the FILELIST can only be altered by a listowner. A simpler method would be to add the other person as an owner for that list. (The disadvantage is that they then share with you complete authority over all aspects of your list, so you will be subject to any mistakes that they might make.) You can send GET <listname> LIST (HEADER NOL PW=XXXXXXXX to LISTSERV. Then add the line * Owner= my.friends@address after the original Owner line that contains your address (taking care to see that the "*" is in column 1, and that a blank follows "="). Also, edit the file so the first line reads PUT <listname> LIST PW=XXXXXXXX . Then send it back to the LISTSERV and you're done. Thereafter your friend can add files, revise and/or delete them (and do any other list-owner function) just as you can, with the use of the list's password just as you use it. I hope you also know some basic rules of LISTSERV file management, such as you need to add a new file's name to the FILELIST *before* you can PUT the new file to the LISTSERV, and you need to delete a file's name from FILELIST *after* you have deleted a file, otherwise your attempt to PUT the FILELIST will be rejected. I'm actually not much more than a novice at this, so please everyone, correct me if I'm wrong. -- Roger Burns, List-owner CFS-L @ NIHLIST Chronic Fatigue Syndrome discussion CFS-NEWS @ NIHLIST Chronic Fatigue Syndrome Electronic Newsletter CFS-D @ ALBNYDH2 CFS File Storage
