I hope you're kidding; or, perhaps mistaken about the sender.
Articles are too easily spoofed, forged, and/or remailed.
If you're not...
There was a problem with a troll in another NG a few years back,
pulled my chain pretty bad, everybody in teh group lost their cool -
this troll started sending lewd emails with large attachments to
people that had filtered his posts, and then he proceeded to stalk
and harass others to the point of issuing bogus complaints to
webmasters and ISP's, trying to get them all booted.
Long story short: He's gone now... apparently, he finally ran out
of ISP's. It can happen!
The point is this: It is very likely someone with a personal
vendetta, doing a "Joe Job" on Chris, et al.
Why do you think I recently started digi-signing my messages again?

THATS A JOKE in itself. The Church of JESUS CHRIST? You mean the one who
said not to commit adultery? The one who, through Paul, stated that those
Christians who seek to do his work would be the husband of ONE WIFE? That
Church? Then drop the Later Day Saints because their ain't nothing 'SAINT
about the mormons.
You are NOT followers of Jesus Christ. He wore a robe NOT LONG UNDERWEAR!

Thanks for the info Steve. I'm printing it out.

Low freon will cause it to ice up and that will cause a reduction in
flow. To test, let the A/C sit turned off for a while until it has
thawed. You can run the fan without the A/C on to help it thaw out
faster. If the air flow returns eventually then you can rule out low flow.

I would think that if the airflow returns after thaw, that low airflow
mighta been the problem in the first place. Hard to tell without gage and
temp readings.

Do good work.
It's longer in the short run
but shorter in the long run.
