We have a simple membership sign-up form. It just collects email, first and last name.
I intentionally left the "No Duplicates" setting unchecked, because we frequently get multiple members (such as husband and wife) using the same email address, and they each need to sign up for membership separately.
This leaves our gravity forms Entries database with lots of unintentional duplicates, because some other folks have trouble with the form and end up submitting multiple times.
How can I run a dedup of some kind on our gravity forms Entries list after-the-fact, to remove truly duplicate entries (where email address, first and last are all identical)?
Thanks!
