Me too, but according to

group-mentors@acpub.duke.edu is a body of volunteers experienced with
the newsgroup creation process.  They assist people who want to
propose new groups with the formation and submission of a good
proposal.  It is strongly encouraged, though not required, that they
be contacted with an outline of the basic idea for a proposal, and a
mentor will work with the proponents to submit a formal proposal.
People who have experience with the process and wish to help others
should contact group-mentors-request@acpub.duke.edu to join.

1) A request for discussion on creation of a new newsgroup should be
  posted to news.announce.newgroups, news.groups, and any other
  groups or mailing lists at all related to the proposed topic if
  desired.  news.announce.newgroups is moderated, and the
  Followup-to: header will be set so that the actual discussion takes
  place only in news.groups.  Users on sites which have difficulty
  posting to moderated groups may mail submissions intended for
  news.announce.newgroups to newgroups@isc.org.  The proposal
  must be in the format defined in "How to Format and Submit a
  New Group Proposal", a pointer to which is at the end of this message.

  The article should be cross-posted among the newsgroups, including
  news.announce.newgroups, rather than posted as separate articles.
  Note that standard behaviour for posting software is to not present
  the articles in any groups when cross-posted to a moderated group;
  the moderator will handle that for you.

2) The name and charter of the proposed group and whether it will be
  moderated or unmoderated (and if the former, who the moderator(s)
  will be) should be determined during the discussion period. If
  there is no general agreement on these points among the proponents
  of a new group at the end of 30 days of discussion, the discussion
  should be taken offline (into mail instead of news.groups) and the
  proponents should iron out the details among themselves.  Once that
  is done, a new, more specific proposal may be made, going back to
  step 1) above.

3) Group advocates seeking help in choosing a name to suit the
  proposed charter, or looking for any other guidance in the creation
  procedure, can send a message to group-advice@isc.org; a few
  seasoned news administrators are available through this address.

   And it goes on and on...

   I ran my own private news server for a short while. If you do that, you
can create any groups you want, but then the problem is getting people to
subscribe to your news server. Eclipse runs their own news server, for
example.
