+There are so many wonderful talks at ${conf-name} this year! I

+will be highlighted with a black border in the schedule, and your
+talk ID${plural} (${slugs}) will be highlighted with a yellow
+background in the notes that follow.${wrap}
+
+As of the time I write this e-mail, your tentative schedule is:
+
+${schedule}
+${availability-note}${timezone-note}I might also be able to move things around if you want to
+attend any conflicting Q&A sessions or if your availability
+changes.${wrap}
+
+Things may have changed a little depending on what other speakers
+have asked for, and we'll also update the schedule as we get
+closer to the conference. I'll let you know if the schedule for
+your talk${plural} changes by more than 2 hours, and we'll send
+the updated schedule along with check-in instructions before the
+conference.${wrap}
+
+We plan to announce the schedule to the general public on
+${schedule-announcement-date}, so we'd love to incorporate any
+schedule feedback before then.${wrap}

+In the meantime, good luck working on your presentation. ${todos}
