EAlerts (Email Alerts)
This feature may be optionally enabled for the module which allows logged in users to subscribe (or unsubscribe) to module content changes. If enabled, there is a checkbox on the item create/edit screen to send out an email alert. If you have NOT selected the auto-send setting, you'll be taken to a second screen after saving the item to compose and then send the email alert. Otherwise, if auto-send is enabled, the email alert is composed and sent based on the e-alert settings. Users may manage subscriptions with the optional e-alerts profile extension.
