The email newsletter will contain information about our activities, links to information about half-Jewish books and films, access to various media articles on half-Jewish people, and much more.

All you have to do is enter your email address in the box and then respond to an email from our website that will confirm your subscription.

By doing this, you can help advise, guide, counsel and socialize with other half-Jewish people from all over the world as they contact our group.

You then will see a check box under your comment asking “Notify me of follow-up comments via email.” Just check that box.


We have more information about our group that is not on the website and is contained in an introductory email that we send everyone who gets in touch with us.

It contains information about why Robin Margolis and our original Board founded our group, what our members are like, and trends we see in half-Jewish peoples’ lives.
