Do not allow one member to register another member on event
It is possible for one member to register another member on the registration form by entering their email address.
Do not allow one member to register another member during registration on event.

This may well be a deal breaker for us. It seems insane that members can sign other members up (i.e. commit them to attending -- even if in our case it is zero-cost) for events without the other member having a say!

We have multiple club members that share a single email address. So one Club member registers themselves and their spouse/partner who is also a Club member.
