User story & summary:
As a mobile web user, I want a cleaner and less verbose account creation form so that I can view all required fields at a glance without scrolling, and complete registration with reduced information overload.
- As a mobile web user, I want simple and clear guidance when creating a username, because then I am more likely to respect the username policy.

Metrics tracked for this experiment:
| Metric | Instrument source |
| Experiment exposures | experiment_exposure |
| Account Creation attempts (= all Special:CreateAccount submissions) | 'creation_attempt' |
| Fraction of Special:CreateAccount submissions with email | 'creation_attempt_with_email' |
| Unsuccessful account creation attempts (= Page visits with error present) | 'page_visit_with_error' |
| Special:CreateAccount Create-Account-button clickthrough | 'create account button' |
| Special:CreateAccount user policy link clickthrough | 'username policy link' |
| CTRs for the links in the username policy TL:DR; | (to be created) |
Unavailable metrics:
Due to an inherent limitation of how test-kitchen works, we only can instrument the Special:CreateAccount form itself (which lives technically on the auth.wikimedia.org domain) and nothing on the origin wiki, so the following are not possible for this experiment:
| Account creation rate | generic account creation instrument |
| Constructive edit rate (mobile web) | edit_saved |
| Constructive edit rate of newer editors (mobile web) | edit_saved |
Acceptance Criteria:
- Implement additional instruments in WikimediaEvents as needed
- adjust Statslib / Prometheus based metrics as need (see respective V1 change)
- Set up A/B test on Test Kitchen
- Release experiment on start date listed above (or communicate if a shift in release is necessary)
- Adjust Growthbook analysis setup as needed
