[TIGGE #LGY-600646]: Re: Missing fields from CMA

YangXin, Manuel, Baudouin, Doug,

I apologize for not sending this note this past weekend...

re:
> I guess you meant to ask Mike to take a look at my LDM Configuration,
> since only he have access to all three LDM Server s.

We had a meeting on Friday afternoon to discuss the configuration of
YangXin's machine and the current TIGGE topology.  I am writing up the
notes from that meeting this morning and will be forwarding them to the
Unidata staff memebers who took part in that meeting for comment/revision.
As soon as we have agreed on the content/wording of the notes, we will
forward them along.

Just so you know, the following Unidata staff took part in Friday's meeting:

Steve Chiswell
Steve Emmerson
Mike Schmidt
Yuah Ho
Tom Yoksas

Again, I will be sending the notes of our meeting -- with recommendations --
later today.

Cheers for now...

Tom
