Developing for Activity2
Activity2 (Activity's DRUPAL-6--2 branch) is a complete re-write of Activity from the ground up utilizing Triggers, a core Drupal module. While Triggers was found to be somewhat lacking, Activity2 works to extend Trigger functionality for it's own purposes. This means that while Activity Triggers will show up in the Trigger UI, you should not edit them there. Activity2 uses it's own term called 'Activity Publisher Templates' in order to configure what and how activities on your site should be recorded and displayed.
