Subject lines in GrADS posts [Re: Questions and CD]

[James T. Potemra]

May I add to Arlindo's response and remind everyone that these emails
are archived in a database, and this database becomes almost useless
with subject lines such as "Please help", or "question", etc.  I'm sure
many mail filters, human and otherwise, delete these on receipt.  Please
try and use a subject line that is somewhat meaningful; this will save
time in the future for those who search the archive.  Thanks,

Jim
