There are some circumstances that it's necessary to allow duplicates.
Mitingu uses email addresses as unique identifiers. This works fine most of the time as an email address is generally unique to the individual. However, there are occasions when someone is booking two people onto an event, but uses their email for both or when an email address like firstname.lastname@example.org is shared by two or more people.
If you want to allow this, we've made it possible to do so. Here's how.....
1. Go to Contacts and select Contact Settings
2. If you would like to allow duplicates then turn the switch off. It is on by default. Save changes and it will be activated
