Each space in Confluence has its own set of permissions, which can be granted and revoked by a space administrator. The user that creates a space, like when you create your personal space, is automatically an administrator of that space, and they can add other space admins if they want to by adding the Space Admin permission to another user or group.
How do you find out who the space admin is for a particular space? Choose Spaces > Space directory in the Confluence header, then choose the Space Details
icon beside a space.
If you're one of those lucky space admins, you can assign permissions for the space to individual users, groups, or anonymous users. To change permissions for a space, choose Space tools > Permissions from the bottom of the sidebar, then choose Edit Permissions to change permission settings.
