The Founder of a region is the nation that created the region. The founder is listed on the region's page, and can access its Regional Controls. This includes the ability to alter the World Factbook entry of the region, set a password, eject nations, and ban/unban nations. The founder may also decide if the region's delegate may have access to the Regional Controls.
The founder was the only member of the region with permission to clear spam posts from the Civil Headquarters board. This privilege could not be passed to the delegate, regardless of circumstances. However, by a recent update, with the storing of all RMB messages, they cannot clear spam posts, but they could suppress them, in which both the delegate and founder is able to do.
A group of the oldest members of a region (including the Founder itself and early recruits) can sometimes be referred to as the founding fathers, founding members or founding nations of that region.
