The PHP / MY SQL5 PHP app shall support 1) Multiple lists As it sound independent , list that are 100% separate and managed separately as we have multiple products to support. on the one server These list are created only by system administrator you will need to provide this Admin interface , it is here the SYS administrator creates the list and appoints the managers , and can access every available list to manage as well 2) Each list is managed by List manager ( remember one or more can be appointed ) An interface must be created ( with password ) so that Management can add to the list , via an on line form.
