Don,
I am pretty sure I see some sort of check box that if I want the group
to be made aware of an upload of a file, I check it.
Correct.
Using that check box generates a notice to members, but those /do/ have a hashtag in the subject.
A moderator can preemptively block such notices from posting to the group by creating the corresponding hashtag and setting the hashtag options. No Email will cause them to quietly post to the group's Messages, but not go out to members by email, Moderated will cause them to be held in the Pending list where you can delete them.
