Turtle, They are just joking, not flaming.

By the way, I unsubscribed at alt.hvac because of all the strife over

I think the problem is air infiltration, which is normal. All houses
that I have seen leak some air. What you are smellng is the moth's
balls outside. :-) Get rid of all of them, both inside and outside.
The smell will go away.
