How is Discourse working?
Do you have any feature in mind? Anything you want to do, anything you are missing?
Well, obviously, the Oauth integration, but there is already a phabricator ticket about that from what I heard.
Also it would be interesting to investigate how wiki/mailling-list/IRC conversations might be turned to discourse threads through some software facilities.
For what I know, discourse permit to use markdown and PHPbb syntax. Maybe allowing a (subset) of Mediawiki syntax would be nice. Or the otherway, on Wikimedia instances of Wikimedia, having a tool to export to to misc. format. Wherever it would be integrated, this could be a simple wrapper around something like pandoc.
Discourse supports mailing list integration out of the box. It is more a social matter than a technical one.
Official plugin for chatroom integration, plus other third party plugins for native chat.
I’d personally request automatic topic closure in certain sections (maybe mailing list sections) after say 30 days so that people can move on and not just necropost.
