I am also a "neo-vintage" member (widowed almost 10.5yrs, joined right after my late husband died). I think the founders just made up their minds that YWBB wasn't relevant anymore, despite the fact that it was clearly still being actively used, despite the fact that those of us who are longer-term widows but no longer active posters still checked back in occasionally. Starting YWBB was a wonderful thing, and I am forever grateful for it. However, the way the closing of it was handled - with no real opportunity for people to step up and fund the board, hand it over to a new board, etc. - was selfish and narrow-minded. There is just no other way to put it, IMHO. Had they given people a real, honest chance to raise funds to keep it going, hand it over to others who might have had more energy/desire to keep it going, etc. that would have been different. But they didn't, and it wasn't right.
That said, it's done, and I knew there was nothing I could do about it except figure out how to live with it. As so many others here have said, it was "a great disturbance in the Force", and another form of loss for so many of us, even if we were no longer actively posting. It's another aspect of our lives that has died. And so, yes, grief, strange though it may seem.
I don't plan to post a lot either, but I may for a while pop in more than I have in the last few years, in part to help the board get going.
Hugs to all!
