How can I hide email address from logged in users?

Thanks for your great ACADP plugin. It is the best directory plugin I had seen so far.

However, I will like to hide the email address on the listing details from everyone, including logged in users. Currently one can only set the email not to appear to the public or non logged in users.

What file do I need to edit to make the email not to appear on the listing details page.

Keep up the good work.
