INN internally shouldn't care too much about what characters you use in
newsgroup names.  However, the Usenet standards pretty much limit the
character set to alphanumerics plus [.+-] (not including the brackets).
Underscore is technically not allowed, but isn't uncommon.

Be careful with some of the other characters, since they're shell
metacharacters and may do odd things if not properly quoted.

    Please send questions to the list rather than mailing me directly.
