If I may add my two cents, I too think that tagging should be done
by the poster.

And yet I have never seen a NG where tagging has been cnsistently adopted.
It seems that people do not care to struggle to find a cathegory for the
problem they are trying to get help for.
This is especially true for nonmoderated NGs, of course.
A moderator could in some way force posters to add a tag if they want their
post to reach the group, by automatically rejecting every non tagged
message, replying to the OP with a message showing the suggested
cathegories. Leaving to the poster the freedom to add a second, more
specific, tag could also allow for a better cathegorization of the messages.

For example, the first level would be necessary to post, the second (and
third, and...) level is facultative and could be picked among a more
extensive list. It could also be 'user defined' so to speak.
This will leave a certain degrre of freedom, since a classification
is not necessarily unique.
Ten big cathegories could do. For example

            Third Party
    [Newbie]
            Installation
            ...

Plus a wildcard:

    [Uncertain]

The tag [Uncertain] can be changed by those who reply. It could lead to
different choices, but then, that's the spirit: allowing for multiple
'keywords'.
For example
    [Uncertain] I can't get it done!
Could become
    [Package][Shapes] I can't get it done!
Or
    [Package][Shapes][Remove] I can't get it done!
Or
    [Newbie][Remove] I can't get it done!
Or
    [Programming][Scoping] I can't get it done!

Since it would be as easy to forge as the 'standard' tagging I'd rather
stick with the old [...] wrapper.

Definitely.

So I am not the only one collecting all this wisdom? : ]

It would be harder for the causal user to set and to take advantage of this
kind of tagging. Moreover, it'd be almost invisible and new users  could not
learn by... example.

I couldn't agree more. Moreoever, certain newsreaders can not sort posts
with multiple Re:'s (or any other non standard prefix) correctly.
As for the length of the line,  if the original poster is using a tag, he
will try to use a shorter description for the subject line.

Multiple tags will constitute multiple keyword in a search.

>You can add one.

To speed things up, there could be a transition period where a bot could add
the [Uncertain] tag, while alerting the user that to post new messages a tag
is required.
If this is done on the already filtered (i.e. non spam) messages, the load
would be sustainable. (60-70 mails per day in the worst case for the first
couple of months)

Oh, well, these were only my two cents.
