OOTY: Yes, shadchanim will be (and could be right now, I have no idea) invited.
Unfortunately, that’s about all I know about it, not being overly nosy. (YEAH RIGHT. Me not nosy. Ha ha ha. I actually just want to keep on my mom’s good side by not sticking my nose in her confidential business.)
I think the point is that shadchanim will now have a wider pool of people to suggest.
