+We tweaked the schedule a bit! Your new check-in information is:

+${checkin-info}
+
+Please check in early so that we can deal with scheduling changes
+or technical issues, and so that we don't worry too much about
+missing speakers (aaah!). You can find the check-in
+process at ${base-url}${year}/speakers/ . ${wrap}
+
+If something comes up, please let us know as soon as you can. Here's
+my emergency contact information: ${emergency}${wrap}
+
+Thank you for sharing your time and energy with the ${conf-name}
+community!
+
+${signature}
+
+p.s. If you need to cancel, that's okay too, life happens. Let me know
+as soon as you can and I'll try to shuffle things around. Thank you!")
