discourse-mediawiki.wmflabs.org is planned to be a pilot for discourse.mediawiki.org, a developer support channel. The plan is documented at https://www.mediawiki.org/wiki/Discourse
[x] [[ https://www.mediawiki.org/wiki/Discourse | Pilot plan ]] drafted by Qgil and then approved(?) by Qgil.
[x] Identification of points to consider before starting, especially things that we might regret when migrating to production.
** [x] Guidelines for pre-SSO usernames i.e. "user your Wikimedia username"? Not needed.
** [x] Clarity about what will happen to the accounts and the content created during the pilot if we move to production. Content and users will be migrated. Users will have to remember the email they used in the pilot to register in the new site with their own accounts.
**  Agreement on additional plugins required from start, if any.
