The in thing nowadays in the Charedi communities in Eretz Yisrael are acceptance committees. This exists in Kiryat Sefer, Beitar and other places. All of the new communities that are opening up (Pisgat Zev is an example) also boast that they have acceptance committees that screen the applicants. I read this week in Hamodia that when the Gerrer Chasidim wanted to start a community in Arad there was an acceptance coommittee in place that wanted to reject them until a woman who was a Holocaust survivor objected. She said that it reminded her of the Selektzia of the Nazis. I think this is something we should keep in mind and I think it not for us to play G-d and decide who is fit to live in our communities.
Overall it’s a good concept, because people want to live with people that they identify with. but it has to be done in good taste,
