QTR-Quadtone RIP

I thought there was a recent conversation regarding grain in digital negatives for Silver Prints. Specifically I'm interested in grain when using Pictorico Ultra Premium. But scrolling through the list of recent conversations I'm not able to find anything on grain. Is there a way to search the conversation topics? If not, anyone have a message number(s) for this topic?
Any help appreciated.
Cheers,
John
