Noted. These functions are for local groups only. I think that
my concept is sound so I'll try to elaborate on the logic to
help me change my mind if you still feel the same way.
When you say that news can forward it, I presume that you mean I
can "forward" it from the reader. I think this affects the message
author and time/date stamp headers, threading, etc. If this is
not what you mean, then I'd be very much interested in existing
leafnode mechanisms to move articles.
Bear in mind that these are local groups only. Our organization
used news as a way of archiving technical discussions that are
relevant to our operation. We don't want to create a zillion
specific newsgroups and have them all sparsely populated, so
we created groups with more generic topics. Down the road,
through usage we see that one thread of topics is prevalent
enough to have its own forum. At that point, we decide to
create a new group and want to move the messages to the new
group with date/author intact. As I understand it,
forwarding modifies the headers. We want to preserve
that record when we re-organize our groups.
The cross-posting issue is similar. A message may be seen to be
applicable to more groups as the local news group list fragments
into smaller topic domains. Again, I want to cross-post the
message while leaving the author/timestamp headers intact.
I am not aware of how to do this through my reader. (Company
standard is ummm... Outlook Express).

:-) Maybe I ought to read it, but, I already understand the concept,
especially if you didn't author the package in the first place...
Sorry, I suppose my comment did sound more personal than I meant it.

Thank you very much for this bit of advice! I would have had no idea

:-) More gems... I confess that I am not well versed in the attack
avoidance tactics. Thank-you again. I do place a fairly hight
priority on trying to keep my stuff safe...

:-) Thanks for the assurance. I don't know how prevalent use of
local groups is. I am only involved in leafwa because I used it
as a shell to hang extra functionality off of. It helps me better
support our use of local groups. If it weren't for this, I wouldn't
use leafwa myself. After doing the work, I offered it to Phil (the
author), and he suggested that I go ahead and work with the local
groups side of things since he didn't use local groups either.
