I'm not sure NS_TOPIC is localizing properly. I switched my local wiki to $wgLanguageCode = "fr" and restarted memcached but:
- Sujet:<topicUUID> didn't work, it's just a regular page.
- Permalinks still use Topic:Nnnn.
- advanced search shows "Topic" not "Sujet"
- Talk:Flow_QA redirects to Discussion:Flow_QA but then shows "Action inconnue
When we get serious about localizing Flow we should enable it on beta labs in other languages: http://de.wikipedia.beta.wmflabs.org , he-labs, ja-labs, etc.
