If you would like to be assigned a PSN number you can go to the
following link and email Dave with the info requested on that page.
You can go to the list and see how other PSNers have filled out
their info.

If you check my info you will see that my first sensor was very crude,,
built all wrong,, (built with steel)  but it worked, The first event I
recorded was the 7.0 event from the Loyalty islands in Jan 1998.
It was a vertical with 1.5 sec period built with trampoline springs
and a 50 lb steel weight.
Enjoy and have fun,
