We covered a lot of ground in this chapter! We went over creating and managing users from within our application, sending e-mails about certain events, and how to receive e-mails and incorporate that information into our application. We also added roles to our users and made our application only respond to certain actions of users with a particular role.

Before continuing, think of ways in which you could improve this application, and try to implement them. For example, you could change it so that the access rules expressions are answered by the models rather than hard-coded values. Alternatively, you could add new statuses to the application and send out different e-mails when those statuses change. Think of all the ways you could make this application better to use for the end user.

After adding some new features, go through the Yii documentation located at http://www.yiiframework.com/doc/ to help you better understand some of the methods and properties we used in this chapter.
