[leafnode-list] Newbie: Running just local groups on Machine..

[Nero Zero]

Hello ye all;

I want to run my installed leafnode just with localhost, hence no 
internet newsgroups for now.. How do I create my own "server list" of 
available newsgroups, so that all different users in turn on my machine 
can use this NNTP blackboard if you will.. It be nice if I can learn how 
the structure is set up in /var/spool/news ... and all
