Dave,
There are two lists. There is a general lists and sometimes gets very
chatty and crappy. Other times its great. There is also a tech list
that is pretty tightly controlled (usually). The tech list is just SO
AWESOME! Just two weekends ago I wanted to replace a vent in my Mooney
and couldn't figure out how to get it out (the maint. manual leaves a
lot to the mind). I had answers right away.

For me, the trick is to NOT use your regular email account to
subscribe. I created an email account in yahoo that I only use for the
Mooney list. I sometimes go months without looking at it because I'm
busy. Then, I'll have an issue and I'll log into that account, ask a
question and get a quick answer. Many of the operators of our Mooney
factory service centers are on the list too (Tom from Top Gun, Paul and
Robert from Lake Aero, Don from Maxwell Aviation, etc). These guys are
the gurus of keeping Mooneys running (and I've had each of them work on
my Mooney).

Anyway, to subscribe go to aviating.com.
