+This module will check whether an attendee already registered with the same e-mail address.
+If this is the case, then depending on configuration, the new registration will either:
+#. Replace the previous one
+#. Be ignored
+
+This module is quite similar in implemented function to event_registration_partner_unique,
+except that you do not have to get a partner for each attendee, you only make check on e-mail.
+Also there is no dependency to partner_event module since it is not needed here.

+
+Configuration
+=============
+
+On event record (on the backend), select "Unique registration email" field if you
+want to enforce unique emails among registrations.
+
+Once selected, new field "Duplicated email registration behaviour" will appear where
+you have to select the expected behavior if an attendee registers with an e-mail
+already registered:
+#. Delete and recreate registration: will remove previous registration and create a new one
+#. Ignore new registration: will silently discard new registration (and keep the previous one)
