The EmacsConf site is built on the awesome Oddmuse wiki software, available under GPLv3+.

We use a number of extensions for the EmacsConf wiki to add additional useful features. Most notably, we use the Namespaces module to allow creation of what are in effect “sub-wikis” for each conference year.

You can see a list of the active extensions over on the Wiki Version page. The Oddmuse config file for the wiki is also available at

We also used to self-host a Discourse instance at, which is now retired and has been replaced with a read-only archive of past discussions (see discourse for more details).
