When I set up my restricted Y! group many years ago, I was able to include a question that applicants wishing to join had to answer before the application would even be allowed through to me. I want to do that to the groups.io group I have set up (or at least know how to retrospectively). It seems this can't be done retrospectively on Y! groups either. I tended to use what the applicant said to judge if they could join or not. Is there a way on groups.io?
