There are few who possess a more encyclopedic knowledge of Pick/D3 than Jonathan Sisk.
In fact, Jon wrote Encyclopedia Pick for the late Dick Pick, inventor of D3.
In so doing, he also embedded it into the platform as an online help
facility which has since mutated into Web form still used and supported.
