This page describes the class of registered users with a new account in a given Wikimedia project but previously registered on another project.
- When a user becomes attached to a project other than the home project, a record is created in the new project database. Attached users are not genuinely "new" and should not be counted as newly registered users.
- An attached user's registration time corresponds to the time of the "attachment" event to the new project.
Attached users (local)
