Warning Danger Avoid Discourse.org
After a week-long evaluation, it is strongly recommend to people considering using Discourse.org's product, to not consider using it in a production environment any time soon. Maybe in 3 to 5 years, if it continues, it can be reeavaluated. The product is far to fragile, and the community support is far below standards.
UPDATE: 20161202 - I can now recommend people instead consider using NodeBB, NOT Discourse. http://nodebb.org Much better community & developer environment, much better documentation, and far less of a kludge product than Discourse. It is not perfect by any means, but a FAR better product than Discourse.org's Discourse mess.
