Hello, Just wanted to clarify my previous post: I would like to automatically create usernames and passwords that the users provide to us on registration. As an administrator, I though that I could do that. >I used the following command to add a new password to listserv from the admin email: >PWC ADD [log in to unmask] nelly pw=12345 (pw=the listserv admin password) >I got the following error message from Listserv: > PWC ADD [log in to unmask] nelly >Invalid password supplied. Acceptable passwords are: the list creation >password ("createpw") and the system file modification password ("storepw"). >Does anyone have any idea what I'm doing wrong? What does the above message mean? Thanks for you help! Nelly.
