Superlists and sublists
A brief description of super lists and sub lists followed by instructions on how to create them.
A super list is like an umbrella list, under which, there are one or more lists called sub list(s). If a message is sent to the umbrella list, then that message will also be sent to the sub list(s). Note that members of more than one sub list under the same super list will not receive the same message more than once.
In order to create super lists and sub lists, you need to login to the web interface.
