+Hi ${name}!
+
+Thank you for volunteering to help with the captions for ${conf-name}
+${year}! Last year, we were able to get almost all the talks captioned
+in time for streaming. Participants found them very useful for
+understanding different technical terms, names, accents, and so on.
+We&rsquo;d love to be able to pull that off again this year!
+
+We&rsquo;ve set up ${backstage} as the backstage area where you can view the
+videos and resources uploaded so far. You can access it with the
+username "${backstage-user}&lsquo ; and the password &rsquo;${backstage-password}&lsquo ;.
+Please keep the backstage password and other speakers&rdquo; talk resources
+secret. ${backstage-use}${wrap}
+
+You can find captioning tips at <https://emacsconf.org/captioning/> .
+You can use your favourite subtitle editor, and you can convert it to
+whatever format you like. If you prefer to work with plain text, we
+can probably even figure out the timestamps afterwards.
+
+Thank you!
