TravelTalkOnline Forums Thread Like Summary - Entry form

I'm having difficulty finding answers to questions on the entry sx web site.
My wife and I are traveling with another couple and I would like to submit the forms for all of us. I'm assuming I can enter as a group but they don't have email addresses. Should I use mine for all of us?? Then print the acceptance?????
Thanks

I’ve done Group for wife and myself twice now with no problems 🤷🏻‍♂️.
