**User story:**
- As the Growth team, I want to understand how Leveling up (part of the [[ https://www.mediawiki.org/wiki/Growth/Positive_reinforcement | Positive Reinforcement project) ]] has changed newcomer behavior, because I want to see if this work was effective and I want to know if any improvements should be made.
- As a Wikimedian, I want to make sure new Growth features are working well for newcomers, because then I'll be more accepting of the changes when they are rolled out on my wiki.
