Hi, ${speakers-short}!

Looks like all systems are a go for your talk. Thanks for
proposing it! Your talk page is now at ${url} . Please feel free
to update it or e-mail us if you'd like help with any changes.${fill}

If you want to get started on your talk early, we have some
instructions at ${base}${year}/prepare/ that might help.
We strongly encourage speakers to prepare a talk video by
${video-target-date} in order to reduce technical risks and make
things flow more smoothly. Plus, we might be able to get it captioned
by volunteers, just like the talks last year. We'll save ${time} minutes
for your talk, not including time for Q&A. Don't sweat it if
you're a few minutes over or under. If it looks like a much shorter or
longer talk once you start getting into it, let us know and we might
be able to adjust.${wrap}

I'll follow up with the specific schedule for your talk once things
settle down. In the meantime, please let us know if you have any
questions or if there's anything we can do to help out!

					"${email-notes}Hi, ${speakers-short}!

There are so many wonderful talks at ${conf-name} this year! I
think we're going to have a two-track conference again, so I
wanted to run the draft schedule by you in case you had any
comments or requests.

You can see the draft schedule at
${base}${year}/organizers-notebook/?highlight=${slugs}#draft-schedule
.  If you use a Javascript-enabled browser, your talk${plural}
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}
Looking forward to ${conf-name} with you!

There are so many wonderful talks at ${conf-name} this year! I
think we're going to have a two-track conference again. You've
indicated that you'd like to take questions after the conference,
so that's totally all right. You don't have to make it to the
time your talk is scheduled; this e-mail is just to keep you up
to date. =)

You can see the draft schedule at
${base}${year}/organizers-notebook/?highlight=${slugs}#draft-schedule
.  If you use a Javascript-enabled browser, your talk${plural}
will have a black border in the schedule and a yellow background
in the notes that follow.

We'll also update the schedule as we get closer to the
conference, but I'll let you know if things change a lot. Anyway,
that's how things are shaping up.

In the meantime, good luck working on your presentation. ${todos}
Looking forward to ${conf-name} with you!

Hope things are going well for you! I got the upload service up
and running so you can upload your video${plural} and other talk
resources (ex: speaker notes, Org files, slides, etc.).  You can
access it at ${upload-url} with the password
\"${upload-password}\". Please let me know if you run into technical issues.${fill}

If you can get your file(s) uploaded by ${video-target-date},
that would give us plenty of time to reencode it, edit captions,
and so on. If life has gotten a bit busier than expected, that's
okay. You can upload it when you can or we can plan to do your
presentation live.
(Late submissions and live presentations are a bit more stressful, but
it'll probably work out.)${fill}

We've also 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}\" and the password
\"${backstage-password}\".  Please keep the backstage password
and other speakers' talk resources secret. This is a manual
process, so your talk won't immediately show up there once you've
upload it. Once we've processed your talk, you can use the
backstage area to check if your talk has been correctly reencoded
and see the progress on captions. You can also check out other
people's talks. Enjoy!${fill}

							"${email-notes}Hi, ${name}!

${conf-name} is in two weeks. Aaah! I don't think we have your
presentation yet, but I'm not panicking (much) because we've got plans
and backup plans.

Option A: You can upload your presentation before the conference

There's still a little time to squeeze in processing presentations and
possibly even captioning them. If you're getting stuck because you
want your presentation to be totally awesome, it's okay, it doesn't
have to be perfect. If it's too long or too short, that's cool too; we
can manage the time around that. We'll figure things out together. =)

You can upload your file(s) to ${upload-url} (password
${upload-password}) and we'll get things going.${fill}

If you're thinking of doing the Q&A in a live web conference,
please also test the BigBlueButton URL described under Option
B. Thanks!

Option B: You can do it live

Sometimes it's easier to do a presentation live, or sometimes you're
making last-minute tweaks and want to play the latest copy of your
video from your own computer. We can do the presentation live over
BigBlueButton. Your room URL is ${bbb-url} , and I've put together
some tips at ${bbb-tips} . Please
help reduce the technical risks by trying out the BigBlueButton setup
before November 28 so that there's time to help troubleshoot.${fill}

Option C: It's okay, you can cancel

Sometimes an interesting talk idea turns out to be more challenging
than you'd like. Sometimes life happens. If you're stressing out and
you don't think you can make it, no worries, no need to feel
embarrassed or guilty or anything like that. Let me know and I can
update the schedule so that other speakers have extra time for Q&A. We
hope you'll consider proposing a talk for another EmacsConf!

----------------
If you're planning to go through with the talk (yay!), could you
please take a minute to check if I pronounce your name correctly in
the intro I recorded? The recording is at ${intro-url} , and you can
also find it under \"--intro.webm\" in your talk's section at
${backstage-url-with-credentials} . If it needs tweaking, you can
upload a recording to ${upload-url} (password ${upload-password}) or
e-mail me the corrections.${fill}

Best regards,

Since you're planning to do a live Q&A session, I've set up a

Could you please take a minute to check if I pronounce your name
correctly in the intro I recorded? The recording is at ${intro-url} ,
and you can also find it under \"--intro.webm\" in your talk's section
at ${backstage-url-with-credentials} . If it needs tweaking, you can
upload a recording to ${upload-url} (password ${upload-password}) or
e-mail me the corrections.

We'll send you check-in instructions a few days before the conference
so that you'll be all set.

Best regards,

You've indicated that you won't be able to attend the conference
itself. That's cool, we'll collect questions during the conference and
e-mail you afterwards. If I got your preferences wrong, please let me
know if you'd like to handle questions during the conference via
Etherpad, IRC, or a live web conference. We'd love to have you join
us!

Best regards,

Thank you so much for being part of ${conf-name} ${year}! Hundreds of people
enjoyed it, and I'm sure even more will come across the videos in the
days to follow.

Your videos are available on the talk page at ${talk-urls} , and
we've added the questions and comments that we've collected from
IRC/BBB/Etherpad. For your convenience, I've also included them below.

Your videos are also available on YouTube and Toobnix at:

${video-urls}

If you want to reupload the video to your own channel, feel free
to do so.  If you let me know where you've uploaded it, I can
switch our playlist to include your version of the video
instead. That way, it might be easier for you to respond to
comments on videos.

If you would like to share more resources or add more answers to
any of the questions, you can add them to the talk page or reply
to this and we can add them for you.

Thanks again for speaking at ${conf-name} ${year}!

		"${email-notes}Hi, ${speakers-short}!

We're experimenting with a new harvesting workflow for live and
Q&A videos this year to make things more predictable for speakers
and participants. Sometimes people have so much fun chatting
after the talk that they might forget that the recording for the
session Q&A will be posted for other people to learn from.

I've trimmed your online videos to roughly when the host left the
BigBlueButton room. There was lots of great discussion
afterwards, though, so I'd love to include the rest of it if
that's okay with you. To make it easier for you to review that
part or reuse what you shared in the Q&A session, I've included
an automatically-generated transcript for the whole Q&A
session. I've indicated the section that got trimmed out of the
published recording with \"NOTE Start of section to review\" in
the transcript. You can watch the session at ${bbb-recording-url} .

- Option A: We could post the rest of the Q&A as is, which lets
  people listen to the conversation and learn from it

- Option B: We can keep the published Q&A video to just the part
  that the host was in, and either you or I can go over the
  transcript to pull out interesting notes for the summary or for
  other posts

What do you think?

				"${email-notes}Hi, ${speakers-short}!

Thank you again for participating in EmacsConf 2023. It was a lot
of fun. We hope we captured some of that energy and awesomeness
in this short conference report at ${base-url}${year}/report/ .
Unedited transcripts are now up for the rest of the talks and Q&A
sessions at ${base-url}${year}/talks - more ways to enjoy the
conference.

We're thinking of experimenting with ways to show our
appreciation for speakers. Actually, it's also part of an evil
plan to see if other people might see the sticker on your
laptop/whatever and then talk to you about Emacs, mwahahaha! And
even if you don't hang out with other people, it could be a
continuing source of warm-and-fuzzy feelings and a
not-so-subliminal nudge to consider doing a talk at next year's
${conf-name}. ;)

Would you consider sending us your mailing
address so that we can send you an ${conf-name} logo sticker? If you
would like one, please reply to this e-mail with the details. We
promise to use your address only for sending the sticker. (Or
stickers, depending on what else Corwin rustles up.)

Thanks again!
