Hello!
Actually Gary the web based mailer behind Yahoo is quite badly
managed, so that will always happen, and unfortunately, Google Mail as
much as I like it does that to. I deleted your address from the reply
up there. However the filters for Google Mail are nearly as aggressive
as the trainers at Fairchild AFB near you were supposed to have been.
(I also have family living in your locality as it happens!)

What he's up to is the typical game that gets played all over the
place, either with Cygwin, or with Linux, or even probably HP/UX, you
try everything. If it works which I doubt he'll learn something, if it
does not which I do not, then he'll learn something.

Other then that, then the blurb above is what I've contributed to this
thread, the one below the greeting is the formality.
