As a step towards simplifying the EmacsConf infrastructure, the self-hosted Discourse forum and Gogs instance will be retired on August 14, 2019.
A traditional mailing list plus our IRC channel will take Discourse’s place and serve as primary means of communication for EmacsConf organizers, volunteers, and participants; covering most if not all the use cases for the forum.
I disabled registration on Discourse a while ago. From August 15th onward, discourse.emacsconf.org will be replaced with a static read-only archive of the postings of the forum at the time.
Don’t forget to subscribe to emacsconf-discuss for discussion and upcoming announcements about the conference.
