Hi We have a user who is a member of a sublist not being allowed to post to the super-list. The sub-list and super-list are both set to Send= Private. He gets a "You are not authorized to send mail to the XXXXX list from your [log in to unmask] account. ......." message from the superlist when he tries to post. I was under the impression that the super-list merge all sub-list subscribers to give a dynamic subscriber list. If the super-list is set to Send= Private, then why can't this user post? He is not set to NOPOST. Any ideas appreciated ... Thanks Scotty
