Different users on the CountryHumans Wiki have access to different functions of the site. While anyone can do most things on the site, including reading and editing, some users can access a few additional functions.
Rollback rights enable the user to use a [rollback] button to revert repeated vandalism to a page by the same user. They can also edit forum and message wall threads, rename files, change the protection settings of pages, and edit protected pages.
If you want to be one of these if you want to be a Rollback, Chat Moderator or Administrator than message Tuba or Swiss.
