GDG- Acknowledements

[Tom Ryan]

For some time now, people have been posing questions on the GDG without
taking the time to send an acknowledgement once an answer(s) is posted.  As
a coutesy, recommend that anyone who seeks information follow up with a
comment on thank you, if for no other reason than to indicate the answer was
in fact received.

Do not know whether anyone else has noticed this, but it seems to have
become common practice.
