I would like to send an email everyday that has a list of nodes that are filtered by certain conditions. I think the Rules module would be a good place to start.
- Content Type named "Issue".
- Field inside Issue that connects a user as Responsible Party for the issue.
- Field inside Issue that defines it as either "Active" or "Resolved".
- Email a list to the responsible party of their Issues that have a "Active" status.
If this can be done with Rules, what event do you have it react to? I would guess the core functionality of it would be put in a component that rescheduled itself every 24 hours. Then the action of the component would be "Send Mail". How would it grab the list of nodes that fulfill the conditions?
