title: Drupal 'Send Email' advanced action
body: <p>I may be missing something blindingly obvious here (I hope so).....I am creating a module in Drupal 6 that consists of some triggers and actions.  in it's simplest form it consists of:</p>
  
  <ol>
  <li>An action which checks for some criteria (event that needs to be triggered once a month per user)</li>
  <li>A trigger which is fired for each user that the criteria is true for</li>
  </ol>
  
  <p>I would like as much as possible to be managed through the triggers / actions interface in Drupal as the site admin is not a developer.  The plan is to use the cron trigger to fire the action in 1. which will then fire a trigger for each user.  The site admin will then be able to create a Send Email action through the actions interface and hook it up to the trigger from 2.</p>
  
  <p>The part I can't get my head around is how the recipient of the email will be specified - the user trigger will be fired from an action run by cron (i.e. not in any user context) - how can I pass in a variable that can be used here?</p>
  
  <p>Thanks,</p>
