"Invitation"? Now, who woulda thunk! That holds some possibilities, but is such an approach a bit more restrictive or subjective than a questionaire or test?

And what about prescreened invitations where the invitor is asked about his invitee profile, and then the invitee gets a sign up test profiled with this data?
G should think about this one day!
