1902.0. "Time to tidy up this conference" by TIMMII::RDAVIES (An expert Amateur) Wed Sep 30 1992 12:08

    This notesfile has reached the startling size of around 50 MB (bytes or
    blocks I don't know as this is all the new host manager passed to me.)
    
    However, it contains 48,948 notes dating back as far as 10-DEC-1987!
    
    
    
    		I propose we rationalise this by deleting all 
    		notes dated prior to  01-JAN-1990.
    
    
    This will remove 14,919 notes, a 30% reduction. This, together with a
    file reorganise which I have passed to the system manager should
    achieve a healthy reclamation of his space. 
    
    A list of all the notes proposed to be deleted is available in 
    TIMMII::UK_CARS_DELETE_PROPOSAL.LIS;1
    
    (a curious thing is it's size shows up as (used/allocated) 1990/1992)

    There are some 'title' notes in there that you probably shouldn't
    get rid of (for instance For Sale, Wanted, Introductions etc...)
    
    I haven't looked through the lot, but other things to consider are
    early notes on a topic which is still used.  Keeping the old replies
    to these may be useful.  Obviously, this might take up more of your
    time and effort than is justified in non-work conference moderation.

Have you tried optimising the file without deleting anything?
have you considered archiving the current conference and starting with an empty
file?

    I've had to do this exercise on a conference before. It's stunning how
    much you can save by a simple reorganise of the file. I can mail you
    details if you want to know how. Aside from that, there are two basic
    ways of saving space. Wholesale deletion such as that proposed, and
    selective deletion.
    
    The former option, especially in a conference such as this, is really
    not a good idea. Much of the information in here is factual reference
    data, of a type that doesn't age. It would be a shame to lose it in a
    non-selective axe-slice.
    
    The latter option is very time-consuming, and requires quite a lot of
    thought. I'd suggest that unless you intend to destroy the factual side
    of this conference, (its only saving grace imho) you drop option 1.
    
    Part of the reason the conference is so large, is that noters have run
    out of control. You need to decide whether it's a chat conference, or
    a reference conference. If it's the later, then you have to moderate it
    strictly. There is a compromise possible, but then you have to be
    alert, and prepared to move notes around to an appropriate topic.
    Because this conference is so large, and so busy, this is an enormous
    task.
    
    Old for sale and wanted notes should be purged on a regular basis, say
    after two weeks. Chat notes, which need to be controlled as to where
    they spread, need to be regularly purged. Noters who start new notes
    need to have themn moved to the appropriate topic. Soon, a conference
    has a tone of regulation and order about it, and the noters respond.
    
    This conference, as has been recently noted, contains a whole pile of
    hot air. Clear that out, and you're more than half-way there. You'll
    need help, ask for volunteers. Also, take a good look at PAN, it's
    vital for this exercise, and for controlling the growth of a conference
    when it's "live".

    Re Selective deletion
    
    *If* this approach is taken, one step would be to do a simple directory
    listing that shows all of the topics and how many replies each of them
    has.  Topics with less than a certain number (10, 20 ?) of replies will
    often contain very little 'reference data' and will generally be
    suitable candidates for deletion.
    
    Others may be old requests for 'dated' information, which may show
    up in the original title (all manual effort to find these notes).
    
    Of course, deleting these threads does not free up so much space,
    but can be done in stages.  If a large enough number of topics can
    be deleted, then I guess that some form of file optimisation will
    then be beneficial.

1902.5Much done alreadyTIMMII::RDAVIESAn expert AmateurWed Sep 30 1992 15:2320
    The file HAS already been compressed. 
    
    For sale, and Wanted have both been purged down to a couple of months.
    
    Starting again is possible, but usually the old conference still hangs
    on as an archive, so space isn't really saved.
    
    Although some of the notes I mentioned may be reference, people don't
    tend to search, but rather just re-ask the same question again.
     
    In my view the best way is simply to remove unwanted notes.
    
    I've identified those that are nearly 2 years and over, another tack is
    those notes that have in excess of 500 (arbitary) replies whittle back
    down to the last 300 (again arbitary)
    
    I would say this conference ably combines reference and chat, I see no
    reason to start heavy moderating.
