                   My name is Dave    the surname is Nelson !!    :)
   the out of office message you got was from the OTHER David Nelson that 
is in
the group.
    LOTSSS is to be gained  cuz the database gives so much more than sensor
data. I started this database many years ago when the PSN group was so so 
much smaller  It has maps showing where everyone is located around the world
and the station data also gives broader info on the types of sensors and 
equip  YOU Must remember NOT everyone has digital systems   and not everyone
that does posts to the group. in fact  there is probably less than 25% of 
the people
in the database that actually regularly post their files !!!
The database also gives email, www site addresses, soil types at the station
and other general comments the station owner has given me to add to the
All this info is available "at a glance"  in the database and isnt 
available anywhere
You are knocking something that has been VERY useful to many people for 
some 15 years   :)
Its good to be able to look at the maps and see how spread out around the 
out PSN group is. and then just by clicking on a selected dot on the map you
can pull up all the info for that station!

Take care
Dave Nelson
In that order  ;)
