+TODO: write this section.
Sending Notification
-To send a message you use ``send(users, notice_type_label, message_template, object_list, issue_notice)``
-where ``object_list`` and ``issue_notice`` are optional.
+There are two different ways of sending out notifications. We have support
+for blocking and non-blocking methods of sending notifications. The most
+simple way to send out a notification, for example::
-``users`` is a list of the users who should receive the notice.
-``notice_type_label`` is the label you used in the previous step to identify
-the notice type. ``message_template`` is just a string, however if ``object_list``
-is non-empty, then ``message_template`` should contain as many ``%s`` as there
-are objects in ``object_list``. These will be replaced by references to the
-corresponding objects in ``object_list``.
+ notification.send([to_user], "friends_invite", {"from_user": from_user})
-For example::
+One thing to note is that ``send`` is a proxy around either ``send_now`` or
+``queue``. They all have the same signature::
+ send(users, label, extra_context, on_site)
+The parameters are:
+ * ``users`` is an iterable of ``User`` objects to send the notification to.
+ * ``label`` is the label you used in the previous step to identify the notice
+ type.
+ * ``extra_content`` is a dictionary to add custom context entries to the
+ template used to render to notification. This is optional.
+ * ``on_site`` is a boolean flag to determine whether an ``Notice`` object is
+ created in the database.
+``send_now`` vs. ``queue`` vs. ``send``
+Lets first break down what each does.
+This is a blocking call that will check each user for elgibility of the
+notice and actually peform the send.
+This is a non-blocking call that will queue the call to ``send_now`` to
+be executed at a later time. To later execute the call you need to use
+the ``emit_notices`` management command.

-``XXX has requested to add you as a friend.`` where XXX is a reference to the

-be a link or just plain text.
+``send`` also accepts ``now`` and ``queue`` keyword arguments. By default
+each option is set to ``False`` to honor the global setting which is ``False``.
+This enables you to override on a per call basis whether it should call
+``send_now`` or ``queue``.
-``issue_notice`` is ``True`` by default but you can set it to ``False`` if you

To allow your app to still function without notification, you can wrap your
