In src/applications/herald/adapter/HeraldAdapter.php, ln 853:
```
self::ACTION_ADD_CC => pht('Add emails to CC'),
```
Herald uses the description "Add //emails// to CC" which isn't uniform with the way that Phabricator indicates someone is subscribed to a task. In Phabricator //users// are added to a CC not the email itself. In fact the user could choose to not get emails. This action description should be updated to "Add to CC %username%" to be more consistent with the interface.
