It’s a lovely idea, which seems to be coming from a really good place. People have been so beautifully supportive on the old forum with cancer, loss, depression, relationship breakdowns. If you do go ahead, more overt moderation would be good.
Not sure I’d feel safe enough to share many of those sorts of things on any forum just yet. Some of the stuff that just happened at the old forum has left me a bit shaken. Still really early days. In time... maybe. YMMV
