ZOOM

The short answer Rufus is that there isn’t.
However there would be nothing to stop you pm’ing a group of members, ensuring they have installed Zoom, and setting up a meeting yourself. My three daughters and I regularly have “family zoom chats” as opposed to individual FaceTiming, I am also following two online courses using Zoom and my book group meet this way.
Good luck with setting one up, I imagine the time difference might be a problem though if you are going into the Northern Hemisphere, but you are a bit of a night owl I think, so maybe not a big problem.

I don't think there's a GN Zoom group Rufus2 I have used it quite a bit but you need a tech savvy individual to set it up and send the link out. I couldn't do it!!

My daughter and her husband ( living in the UK) often use Zoom to video chat with family in Australia.
