The Developer Relations team at the Wikimedia Foundation is proposing an idea: to have a single place to provide technical support.
We started this pilot based on Discourse: https://discourse-mediawiki.wmflabs.org/
You can learn more about this pilot at https://www.mediawiki.org/wiki/Discourse
In this session, we can quickly demo the Wikimedia Developer Discourse site (including the admin inteface) and then gather ideas, answer questions, and generally discuss next steps.
The current five admins of this Discourse instance happen to be at the Hackathon, and also some of its top contributors. Should be fun!
