[news.misc] valid newsgroups ??

stevens@hsi.UUCP (Richard Stevens) (11/23/87)

A week ago I got mail from the news system saying that there were
"Problems with your active file" and there were a list of about 50
newsgroups that it said were invalid and should be removed.
These were comp.ai.edu, comp.ai.vision, comp.editors, comp.lang.asm370, ...
I went ahead and executed the command it suggested to delete the
groups and all was fine.

Then 4 days later I get mail saying that all of these groups were
missing from the active file and should be added, so I went ahead
and added them.

Can anyone shed any light as to what's going on ??  Thanks.
(What prompts these mail messages to be sent - is a specific news
message received that causes the active file to be checked ??
If so, how often does this occur ??)
