All across the internet we find guides and tutorials on how to keep your WordPress site secure, and they all approach the concept of user roles, but not many actually approach the capabilities of those roles.


The way the capabilities are handled on WordPress make it quite easy to change what each role is allowed to do.

How WordPress Sets Role Capabilities
