I see all these discussions of mailing lists vs newsgroups etc. This is fine reasoning. However, as I understand it, there are no fixed volume numbers required to get a rec newsgroup. We must be persuasive to pass the rec.sport.unicycling newsgroup. However, just because our mailing volume is way below the recommended value for becoming a newsgroup, doesn't mean we should give up.
Daily volume is just one small aspect of a new group proposal.
Again, Seth makes a very important, maybe even critical point.
