Not logged-in user in a customer portal site

Question

How do I get the list of users who have not logged into a customer portal site at all?

Answer 1

Salesforce's reporting transformer can also be used to produce a report, you'll want something similar to this:

Except you need the list in the code for some reason (for instance, for integration with another system) then you should use the reporting engine and then you can schedule it for email delivery, etc.
