An event communication system involves facilitating entry by a user of one or more device addresses via a network accessible user interface of the event communication system. The device addresses are associated with alerts provided by the event communication system. Test alert messages targeted for the device addresses are sent via the user interface. The system sends alerts user devices corresponding to the one or more tested device addresses in response to predetermined events. The system may provide user access to historical copies of data relating to the alerts. Registration on the system involves storing a personal identity data of a student on a database and comparing the personal identity data to registration data entered via the user interface. Authentication is automatically provided based on the comparison.
