Inform news-answers-request@mit.edu of the new frequency, unless you
have a Posting-Frequency line in your auxiliary header; in that case,
just change that line.  In either case, you do not need to await
reapproval from us, unless you are also changing other headers that do
require approval.

We only require notification if the posting frequency changes, not the
actual posting date.  For example, you do not need to notify us if you
change your posting date from the 1st to the 6th day of the month, if
our records indicate your posting frequency is "monthly".
