Nice one, Malcolm! Cheers, Marty.
(Re setting the next competition, Malcolm, as you noted, it normally runs Tuesday/Wednesday, and is usually posted on the Tuesday morning. Some setters, however, find it more convenient to post late on the previous evening. It's not surprising, given the variety of time zones the contestants live in, that there is no strict rule as to the time the challenge is set. In other words, suit yourself!)
