The RedHen Activity module uses the Message module to provide a log of activity in your RedHen instance.
User Interface (view only):redhen/activityredhen/%/%/activity
Configuration:admin/people/permissions#module-redhen_activity
Enabling the Activity module provides a log of actions taken in RedHen by all Users, including creation and editing of all manner of RedHen Records. This activity is displayed on an Activity tab for Organizations and Contacts, listing only Activity related to that Record, or on a central page displaying all RedHen Activity. The interface offers additional filtering options to help you find what you are looking for.
Like RedHen Registration, RedHen Activity requires minimal configuration because it is purely informational. However, access is controlled by a permissions setting.
