Sad news...rc will be missed.
On a personal note...just based on my experience caring for my father before he died, RC must have been an incredibly strong person to accept with good grace that his "retirement" was really the start of a new, unwanted, unpaid, unplanned, overlooked, and too often thankless career caring for someone with dementia. I admired the knowledge and generosity he demonstrated here, but it sounds like what he showed here was truly the tip of the proverbial iceberg.
