Hello, A few hours ago, Wikimetrics ( https://metrics.wmflabs.org/ ) was updated with the following enhancements: - Upload (create) a new cohort and select an option to expand your cohort to include each user's accounts on every other wiki that user has visited while being logged in. See the details of the user story here <https://www.mediawiki.org/wiki/Analytics/Wikimetrics/Stories#User_creates_cohort_with_CentralAuth_insertions> . - Bug fix <https://bugzilla.wikimedia.org/show_bug.cgi?id=71255>: Downloding reports in CVS from large cohorts would timeout/fail. The code has been fixed and optimized to allow this now. As always, feel free to comment and ask questions on this list. We're listening! Kevin Leduc Analytics Product Manager Wikimedia Foundation
