+== Getting a copy of a message
+
+You may want to reply to a mailing list message that you do not have a
+copy of in your mail client, because you are not subscribed to the
+list or because you subscribed after the message was sent.
+
+To do this, find the message you want to reply to in the
+https://spectrum-os.org/lists/archives[public-inbox list archives],
+click on the "reply" link at the bottom of the message, then click the
+"mbox" link.  Save the result to a file, then open it in your mail
+client.  This should import the message and allow you to Reply All to
+it as normal.
