David-
Don’t give your personal information, just the name of your Rov. His address can be looked up by anyone who is interested. You should tell him to expect calls from us. He will obviously confirm all you have said. We can send checks made out to his k’hilla, earmarked for your use. You & I will never meet, no one except the Rov will know your personal details, it will be matan b’sayer without any internet exposure. What do you think?
