I've just been able to check back here, and am deeply saddened by the loss of Sinc... I am new enough to the online community to have only crossed paths with Sinc a small number of times... His reputation preceded him, he lived up to it when I met him, and I am sure his memory will live on in kind.
Despite my not knowing Richard personally, as so many of you do, even I know that we have lost a bright burning candle:
"There are two ways of spreading light, to be the candle, or the mirror that reflects it." - Edith Wharton
R.I.P. Sinc.
