Got a question about Rules module capability before I jump in.
I have a CCK data type which tracks performance dates and volunteer staff assignments at a local non-profit theatre. Note that I'm NOT using the Events module here nor the Events Manager Reminder module which apparently have not been ported to Drupal 6. I am using Date and Calendar.
Every month or so I send out an e-mail reminding volunteers to check their work schedule online. I'd like to add the capability to have the site (using cron) generate notification e-mails every day reminding specific users that they are scheduled to work 2 days from now. Basically a system to dispatch 48-hour advance reminders.
Most of the reading I've done regarding Rules is geared toward system or user events (content publication, edits, etc.) triggering actions. Can Rules also be structured to look at my CCK performance date and volunteer fields to drive my intended notifications?
If the answer is yes, please feel free to elaborate. If this is workable I'm confident I can structure the rule(s) that I need but don't have a lot of time to spend learning how to do it right (and there don't seem to be a lot of examples geared to rules of this nature).
