I create a list, called, say, List-A. List-A has no subscribers of its own. List-A's headers define five Sub-Lists (say, List-1, List-2, etc.) that have subscribers of their own. I then create a list called, say, List-B. List-B has no subscribers of its own. List-B's headers define one list as a Sub-list, specifically, List-A. Question: Who will receive postings to List-B?
