In the List header of the Student list: Send= (FACULTY),confirm where "FACULTY" is the other list. Note, carefully however that since "spoofing" or forging of the From: address is trivially easy, the ",confirm" is required so that whoever posts a message will get back an OK/Confirmation command from LISTSERV, which they must reply to, to actually allow their message to be sent. In event of a forgery, a faculty member will still get the OK/Confirmation, but they should know they did NOT send the message and thus they should NOT confirm it. In all cases, they are STRONGLY advised to double-check and read any message before approving it. Although some may complain that the OK/Confirmation process is too difficult, all I can say is if you don't implement this, the list will be so easily 'hacked' that you might as well set it to Send= Public and learn to enjoy the resulting chaos.
