I want a place for our users to hold discussions, ask questions, etc, that aren't bug reports or feature requests. We'd be lost at Stack Exchange, as the community is too small. I'm looking for an app like Discourse that is integrated with github. I've used gitter on other projects, and found the endless stream format awkward. What do you use for your projects? The only 'must haves' are sign-on-with-github-account, and asynch communications.
