What are Roles?
The identity a particular user assumes in a blog is called their Role. A Role essentially describes the set of tasks, called Capabilities, a person is allowed to perform. For instance, the role of Administrator encompasses every possible task that can be performed within a WordPress blog. On the other hand, the Author Role allows the execution of just a small sub-set of Capabilities.
