At least that’s what the
low field is meant to do.
However, for efficiency, C News doesn’t update this field. This wouldn’t be
such a big loss if there weren’t newsreaders that depend on it. For
instance, trn checks this field to see if it can purge any
articles from its thread database. To update the
field, you therefore have to run the updatemin command
regularly (or, in earlier versions of C News, the upact
perm is a parameter detailing the access users are
granted to the group. It takes one of the following values:
Users are allowed to post to this group.
Users are not allowed to post to this group. However, the group may still be read.
This group has been disabled locally. This happens sometimes when news administrators (or their superiors) take offense at articles posted to certain groups.
Articles received for this group are not stored locally, although they are forwarded to the sites that request them.
This denotes a moderated group. When a user tries to post to this group,
an intelligent newsreader notifies her of this and send the article to
the moderator instead. The moderator’s address is taken from the
moderators file in

another group, namely
real-group. All articles

In C News, you will generally not have to access this file directly.
Groups can be added or deleted locally using
addgroup and delgroup (see the

newgroup control message adds
a group for the whole of Usenet, while a
rmgroup message deletes a group.
Never send such a message yourself! For

active.times file is closely related to the
active file. Whenever a group is created, C News logs
a message to this file containing the name of the group created, the date of
creation, whether it was done by a
newgroup control message or locally,
and who did it. This is convenient for newsreaders that may notify
the user of any recently created groups. It is also used by the
NEWGROUPS command of NNTP.
