Don't get discouraged - or impatient
------------------------------------

After you have submitted your change, be patient and wait.  Reviewers are
busy people and may not get to your patch right away.

Once upon a time, patches used to disappear into the void without comment,
but the development process works more smoothly than that now.  You should
receive comments within a week or so; if that does not happen, make sure
that you have sent your patches to the right place.  Wait for a minimum of
						     ^^^^^^^^^^^^^^^^^^^^^
one week before resubmitting or pinging reviewers - possibly longer during
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
busy times like merge windows.
