Subject line prefix

["Charles S. Harris" <xchar@xxxxxxxxxxxxxxxx>]

On another mailing list, niteowl@slumberland, they've been
debating whether to add a distinctive prefix to their Subject 
lines, to make filtering and filing easier.  I just sent them
the following comment:

   First I chuckled.
   Then I thought "Great idea!"
   Then I thought "Uh oh, not ZZ!" because another mailing list that
I'm on deals with software called Zigzag, and I know they use a
Subject line prefix.
   When I checked, though, I found that the Zigzag list doesn't use ZZ.
Their official prefix is "[zigzag]".  However some of the individual
contributors also use their own prefix, such as ":zz:".
   This leads to Subject lines like:
       Subject: [zigzag] Re: [zigzag] :zz: Re: [zigzag]
           Re: [zigzag] :zz: Childhood influence on ZZ?       :-)
