I think a group sounds like a great idea and just the sort of thing to help. While it might take some time initially to set up once it’s sorted the work is done. I had a small private forum years ago with maybe 20 members and it was the best thing.
I really think I’m going to try setting it up. It’ll be a bit of leg work, but I think the need for it is overpowering the initial reaction to hide from any sort of effort.
