Permissions let you control what users can do and see on your site. You can define a specific set of permissions for each role. (See the Roles page to create a role). Two important roles to consider are Authenticated Users and Administrators. Any permissions granted to the Authenticated Users role will be given to any user who can log into your site. You can make any role the Administrator role for the site, meaning this will be granted all new permissions automatically. You can do this on the User Settings page. You should be careful to ensure that only trusted users are given this access and level of control of your site.
