Configuring your applications and services

In the previous sections, you have further advanced by adding missing components to the user registration process and even localizing parts of the Tic-Tac-Toe application. However, you have always simulated the email confirmation by setting the user confirmation programmatically in code. In this section, we will modify this part to really send emails to newly-registered users and make everything fully configurable.
