Do you mean that the spammers are forging email addresses of MathGroup
participants and using these to post messages to MathGroup
(mathgroup at wolfram.com)? I can see how that would make things more difficult
to filter.
If I understand you correctly, requiring individuals to "register" with
you, possibly listing multiple email addresses, and bouncing email that
is not from registered participants, with a message telling them how to
register, would not work.
Because I usually post from a news reader, my messages have the
following field:
Newsgroups: comp.soft-sys.math.mathematica
Could this be used as a filter (or do spammers forge this as well)?
[As an aside, a solution to SPAM needs to be found. To me, it should
cost money, only of the order of a couple of cents, to send any email
message. You would need to purchase a valid one-off "e-stamp", using
some form of encryption technology, from some site (I'm suprised that
the automatic billing sites have not already done this). Then only valid
e-stamps would be routed though the network. There are, of course, many
issues with this proposal ...]

To me, one of the major limitations of MathGroup is that we cannot
attach Notebooks (without including them in the body of the message).

Actually, if the Subject line included question categories as is being
proposed, couldn't you use this as the primary filter (or again, do
spammers forge this as well)?

As I read MathGroup in a newsreader or sometimes via Google at
http://groups.google.com/groups?q=comp.soft-sys.math.mathematica
I do not see the numbers or the []. Google seems to handle threading
better than my newsreader.
The numbers do not appear at
http://forums.wolfram.com/mathgroup/archive/2004/Nov/
until you click on a particular message so I'm not sure exactly how they
are useful (but then again, I avoid mailing lists and prefer to use
newsgroups or the web). (And I wonder why the Mathgroup archive is not
threaded?)

I did not realise exactly how big a task you face.

It would be best if contributors did such a categorisation for you, i.e.
at the time of posting.
> What would it look like?
Instead of [], another suggestion would be (mock Mathematica syntax
using /:), e.g.,
Statistics /: Chi-square test
This would also be harder to forge and should still be easy to filter.

I imagine that it would have little effect, except the desired one of
allowing better filtering.

Surely that is exactly what they are designed to do.
And I could filter the messages into subfolders of my MathGroup folder
automatically.

This idea has merit and, again, it might be harder to forge, but I don't
know enough about these headers.

Nested Re: Re: Re: ... already does this, though Google handles this
very well, in its threading, dropping all Re at the top level, listing
only the subject, and then listing the contributor for each item in the
thread.

Sometimes categorizations have to change. You could have
Numerics -> Graphics /: Accurate plotting
when there is such a change.

I don't think that this is true.

Not a big issue, I think. I think the group will come to consensus on a
categorization, or move on to a different categorization as required.

I would hope that it would greatly _reduce_ your moderation time.

I do not see why.

There should be a list in the rules section at
http://smc.vnet.net/mathgroup.html

You can add one.

Unlikely, I think. However, I expect that the archive has grown
exponentially and will continue to do so.

I expect that it is used on other newsgroups, but I have not seen it, or
there are subgroups.

sci.math.symbolic

It was intended as a suggestion to reduce your workload, to speed up the
rate of posting to MathGroup, and to improve the automatic filtering
(and threading) of messages.
