I'd like to set up notification schemes so that certain groups of people get an update based on a custom field that contains a group name.
So the use case would be:
Notifications are sent based on that customField value. So IssueUpdated should send an email, but first it should check the CustomField: Groupname and send an update based on that.
Has anyone done that? Or can guess how I'd do it? 
Thanks,
Hollie
