A notice to early birds.
Hi Woodlouse, when you post a comment at 8:33 on Saturday asking for help, I'm reminded of the history of explorations and warfare. If you make an early start and outstrip your support group, then you must accept the consequences of your own ambition. I'm glad that DJA was available to help you, though not sure how happy he is to be referred to as 'et al'. For future information, I've only once begun the puzzle on Friday, when I had weekend commitments but Friday evening open : a colleague from this forum sent me the puzzle online, and I was able to complete it before I went away. Usually I don't begin the puzzle until Saturday afternoon, sometimes considerably later.
