Our goal for the end of June is to have Flow on a whole namespace on one of the WPs.
Catalan is excited and happy with Flow. They'll be using Flow on their 5 Village pump (La taverna) pages soon (DONE), and they'd like Flow on the administrator noticeboards, once we've got the ability to hide resolved topics.
We'll need to talk some more with the community about blockers for full namespace deployment. This ticket tracks the known blockers.
The first namespace proposed by the ca.wiki community is Viquiprojecte_Discussió. The next candidate proposed is Viquipèdia_Discussió. The second namespace can be migrated to Flow only after leaving enough time for testing the first migration, and only when the new blockers found (if any) have been solved.
