I’ve recently got involved in shidduchim but I only work with people I know and they trust that I won’t send them an off target idea. It might not be for them but it’s in the ball park I see the need many more people should get out there and try to network and set up people they know.
So you don’t rely totally on the shadchanim who already are bombarded with calls/emails.
So your average couple can think off ideas and start working on dates for people they know personally. Believe me both the guy and girl will say yes to you more than a shadchan who really is matching up 2 papers.
