This is an example of how the Net will be structured.
        (Also, see NODES.LST)


                                  Level  0
                      +----------(Net Host)----------+
                      |                              |

         |                        |                  |            |
         |                        |                  |            |
      Level 3                  Level 3           Level  3      Level 3
       (Hub)          +---------(Hub)             (Node)        (Hub)
         |            |           |                               |
         |            |           |                               |
     Level  4     Level  4    Level  4                        Level  4
      (Node)       (Node)      (Node)                          (Node)


        Level 0  Is the Net Host or Main Hub.

        Level 1  These are Regional Hubs and poll the Net Host.

        Level 2  These are Hubs that poll a Regional Hub.

        Level 3  Hubs that poll from a Level 2 Hub.

        Level 4  Boards that poll from a Level 3 Hub.

        Generally, boards that have other boards polling mail from them 
        will be considered as Hubs, and those that do not will be Nodes.

        NOTE: Level 4 Nodes can be Hubs for their LOCAL calling area
              only IF they meet the requirements of a Hub and get the
              approval of the Net Administrator.
