Autoconfirmed is a user group that is automatically given to registered user accounts that are more than a day old and have made at least 5 changes. It allows users to move pages to a different title, to create new pages, and to make changes to pages that have been semi-protected by administrators.
The main reason for having autoconfirmed status on Gallowpedia 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.
