Sounds like an approach that's worth trying, Rob.  I've signed myself on 
to the list, giving a grand total so far of two members.

Let's just be clear that Rob and I are agreed about the purpose of this 
new SB_Nerds-R-Us group, then:

- It isn't supposed to be in competition with any of the existing sb 
lists, but to provide a place where monitoring methodologies and results 
can be deposited and discussed.  All the main points from that 
discussion should be summarised and posted on the other lists.
- It isn't limited to any one type of climate, but I hope the discussion 
will recognise that what is appropriate for one climate is not 
necessarily appropriate for another, so hopefully in time we will come 
up with relevant monitoring strategies for different climate zones.
- Any level of monitoring, using any type of monitoring equipment, is a 
fit subject for discussion.
- Subject matter isn't necessarily limited to moisture, but that's where 
we start.
- It is international, and the insights from all national/continental 
building traditions are to be welcomed, as is constructive criticism.

Is that OK, Rob?

I will let people know when it's ready to start properly.  Meanwhile, 
those people who have already approached me privately about moisture 
monitoring, please be patient for a few days while I assemble all the 
"one of the first things" items that Rob identifies below (plus a few more).
