Oops, I noticed at the last second that you don't want users 5-10 to post to the list, either. Try setting up the list as an edited list, and make users 1-4 editors: * Send= Editor * Editor= User1@HisNode * Editor= User2@HerNode * Editor= User3@ItsNode * Editor= User4@SomeNode If a user who isn't defined in an "Editor= " section tries to post, his post goes directly to the first editor, who for all practical purposes should be the list owner. HTH.
