Gosh!!!! I think I'll go and have a stiff drink. I've been a good chap today, the muse settled on my shoulder and I've set next week's 5 today. When ye were referring to #4, I was looking at #4's solution for next week and that IS commonplace.
Are you getting all this???
Ooooooh! Where's my bottle of Jura 12-year-old. Sorry.
