So sorry to hear of your loss. Richard was such a helpful, and profoundly likeable contributor to the forum, he will be greatly missed. It is no surprise that someone who gave so freely of his time and considerable knowledge in life would have taken steps to do the same at the end of his life, and I'm sure the knowledge he has helped others would have done a little to temper his sadness at leaving his friends and family so abruptly .
Thank you so much for thinking of us at such a difficult time, I'm sure everyone on the forum sends you their love and best wishes.
