News groups and news articles should have the same control protocol.
Hence, anything you can do to an article, you can do to a group.
(I.e. make it permanent, give it a different expiration date).
One other possibility is when the articles go to zero, the group
dissappears (suggestion of rabbit!ark). Only problem is that
people can have different expiration criteria on different machines.
Hence, on one machine a group would expire while on another it wouldn't.

Anyway, newsgroups should definitely expire!
