Ard Wiki:Autoconfirmed users
Autoconfirmed is a user group that is automatically given to registered user accounts which are more than 4 days old and have made at least 10 changes. It allows users to move pages to a different title and make changes to pages that have been semi-protected by administrators.
The main reason for having autoconfirmed status on Wikipedia is to prevent vandalism and other types of disruptive changing to popular pages by allowing only users who have shown they can make only good changes to change these pages. It can only be removed if the user triggers the change filters.
