So, only the host would have to add those people, correct?
I wonder if a non-host can add people once he's in. That way, people would only need to have their clan-mates added, and one person from the clan they're adding. Then that person could invite all their people.
It's still going to be a huge and completely unnecessary hassle.
That's the way it works on MKWii. Join a friend room, and if you and the other person have space, you can register them.
Usually for Wars, people have a host, and he adds everyone racing.
