Your reply, with quotes attributed to me, contained none of my words!  These
were Steve Lane's suggestions.  Please take care when quoting others.  I merely
build something that fits a few of the contrary suggestions, simply because
building pneumatic robots is one of my niches.

As I said before, I have nothing against GBC and have experimented with it
myself.  In fact I was waiting for years for someone to do it, since it is such
an obvious thing to do with Lego robots.  I have seen how GBC is good for team
participation and exhibition.  This raises the same problem as with train shows
- you must never let the shows overtake the enjoyment of the hobby for what it
is.  I have enough trouble with self-set 6-month deadlines for my own train
layout, let alone group-set deadlines for building modules that will work with
others' contructions!  I firmly believe in keeping my promises, so I don't take
on any deadlines unless I am certain to achieve them.

If you look at my Brickshelf:
http://www.brickshelf.com/cgi-bin/gallery.cgi?m=mbellis
you will see that I am the sort of person who likes to set their own standards
:-)  Trains to an almost-unique scale, for instance.
