TOPIC: Group size: 1

I need to be able to book children's parties. These will be paid for by a parent so I need to be able to enter the child's details (as the attendee) and the bill payers details (to pay).
The configuration screen only allows groups of 2 or more. How can I edit this so groups of 1 child can be registered (one child attendee and one adult bill payer - non attendee)?

Thanks

DT Reg allows you to create group registration with a minimum of one member. If you are looking at the backend demo, I think that's using an older version from before that option was added. The capability has been there for a while though.
