The Jewish Federation of Greater Binghamton is asking community members to update their phone numbers and e-mail addresses by contacting the Federation office at 724-2332 or “Sometimes we can’t reach many people because the phone numbers we have on file are no longer accurate and we do not have people’s e-mails,” said Sima Auerbach, executive director of the Federation. “If you’ve changed your home or cell phone number, or e-mail address, or would like to be contacted by e-mail, please let us know.”
