+
+EmacsConf 2025 was held on December 6 and 7 as an online conference. We had 25 talks across two tracks on Saturday and one track on Sunday, with a total of 11.3 hours of presentations (including 5 live talks), 5.2 hours of Q&A via web conference, and lots of lively discussions across IRC and Etherpad. There were around a hundred viewers each on the General track and the Development.
+
+We posted videos and transcripts on talk pages shortly after they started streaming, and the recordings of live talks and Q&A sessions are now also available. We've also archived questions and commetns from IRC and Etherpad onto the talk pages. You can find the talk pages at https://emacsconf.org/2025/talks . The videos are also available on [[https://media.emacsconf.org/2025][media.emacsconf.org]], [[https://www.youtube.com/@emacsconf][YouTube]], and [[https://toobnix.org/c/emacsconf/videos][Toobnix]].
+
+Overall, people said:
+
+- Awesome conference as always

+
+* Process improvements
+
+This year, we tried out the following experiments:
+
+- We used our own BigBlueButton 3.0 server to host Emacs meetups throughout the year in addition to EmacsConf.
+- We upgraded Etherpad to version 2.5 for security fixes.
+- We added [[https://gitlab.com/jun8git/sub-seg][sub-seg]] and various [[https://github.com/sachac/subed][subed]] improvements to our captioning workflow.
+- We resumed restreaming to Toobnix in addition to YouTube and Icecast.
+- We adapted to host availability by asking speakers to read their own questions as needed.
+- We modified our [[https://emacsconf.org/mpv/][mpv.conf]] to display the time remaining in the lower right-hand corner. This helped with time-keeping.
+- We wrote more code to simplify updating YouTube, Toobnix, and other places.

+Please keep an eye out for interesting things that

+We'd love to get talks at all levels of experience
+and about lots of different kinds of interests.
+Previous speakers wrote:
+
+- "I always got the feeling of being heard and
+  welcome in spite of the vast distances and
+  cultures separating us. This community always
+  feels like it is open to new members any time.
+  With regards to the conference process also, it
+  was a microcosm of the bigger community and
+  hence I got the same feeling. You didn't have to
+  be an expert or a person who's been using emacs
+  for a long time to talk about something useful
+  for the community. Even the struggles of a noob
+  may be useful for someone else in the
+  community."
+- "I can honestly say though that I had a great
+  time putting my talk together. I hope people
+  will have a good time listening to it. Now that
+  the work is over, I can say it was worth it. so
+  I recommend it warmly"
+- "This has been an all-around fantastic
+  experience, both as a first-time attendee and
+  speaker. many thanks to the volunteers who make
+  emacsconf possible, and the other speakers for
+  their wonderful talks (many of which i'll be
+  reviewing now that i'm not so busy preparing)"
+
+If you'd like to volunteer for EmacsConf, check
+out https://emacsconf.org/volunteer/ to see if
+anything resonates with you, and e-mail us at
+mailto:emacsconf-org@gnu.org. We'd love to have
+you on board.
+
+Hope to see you next year!
