To All Project Coiler Respondents,
I have already forwarded to Malcolm all the data I have received
via responses to Project Coiler so far. If you have the additional
information that he needs, please send it to Malcolm.

All of us benefit from research such as that being performed by
Malcolm and others. I will continue to make available to anyone
who needs it the results of my own information gathering efforts.

I have e-mailed copies of *all* the responses I have received 
so far to Project Coiler to each person who responded to me. Actually
that only amounts to a half dozen or so persons. I am appending
a slightly revised copy of the Project Coiler information coupon
to the end of this e-mail in the hopes that others may see fit to
contribute something. I have included in it the info that Malcolm
is seeking. If you don't know the answer to any item, just leave
it blank. I would rather have incomplete responses than *no* responses!

E-mail responses directly to tom_mcgahee-at-sigmais-dot-com  and I will 
see to it that YOU get a copy of all the other responses received to
date, and I will also forward copies of all data received to 
Malcolm Watts as well.


OK, now here is the Snip Out Coupon that you can fill in and e-mail to me.
