Client is thinking about several date fields for a contact eg, when are they available to start volunteering' and want an alert for it. My presumption was 'oh let's do it with Activities' but actually I wondered if CiviRules could do this.
I ran a test and saw I can use Field value comparison, and set the field to 'is equal to' - but assume that NOW won't work out-of-the-box but happy to be told otherwise.
Assuming not, can you give me a pointer or know if this has been tried and is 'too hard basket'?
EDIT: so a custom field shows 'date i am available to volunteer' for a volunteer which will be sometime in the future. And the Admin want to get a reminder/notification say 5 days before that date is reached.
So I think the Linked Condition is eg Condition = Field value comparison, and Description is Contact.custom_127 = NOW
And Linked Action would be: Add Activity to Contact. Type: Email. Status:Scheduled. Subject: check availability. Assignee: Peter DavisFZ
BUT if it ends up needing to be an Activity then I can also think about creating it at the outset on the form.
Reason I wondered about CiviRules is that I though "ha, with civicrm entity I can probably trigger a notification directly via Drupal Rules", and then i remembered CiviRules and wanted to find out more of what it could do ;-)
