I really liked BND's comment, but I do think that LIssie has had a particularly difficult time. She has so unstintingly supported others, and it seems good that if she cannot post, then we shouldn't just 'let her go' UNLESS that is her express wish.
A thread for Lissie is not a sign that others are not valued. The combination of Lissie's contribution, and the very horrible treatment that she has received from her h do seem extraordinary to me.
