If your downstream sites decide to keep NJE, they will need to move their
connection to  another site,  which will become  their upstream  node for
NJE.  The LISTSERV-NJE  topology will  follow automatically.  Your server
will be linked to a suitable  LISTSERV-NJE server acting as a gateway (so
that NJE users  sending a GET XYZ MODULE command  to your server actually
get a NJE file  in their reader). It can also be linked  to any number of
other NJE or TCP/IP servers.
 
If  your   downstream  sites   decide  to  leave   NJE  and   migrate  to
LISTSERV-TCP/IP, their servers will (presumably) be linked to yours, with
yours being linked to a NJE server as described above. There is, however,
no fixed rule;  we'll just do whatever is best  for spreading the traffic
and minimizing the load.
