hundertsieben, So. I wrote an e-mail to the hasidic-liberal synagogue two weeks ago. They didn't answer so far.
They have no public phone number (anymore), but active social media accounts, which I could contact.
Should I wait? Or not?This might have been easier two months ago, and I'm afraid something might happen and it will become much harder. I could also send them a membership application, since they offer this publicly. I think it's weird though.
