I remember well an EV from about a year ago where all the single or double letter combinations had to be substituted for their periodic numbers. I think the title was Occasional Furniture, which I liked.
MM, a huge congratulations for managing the Salts puzzle!
Jigjag, I was surprised at how long ago the Salts puzzle was, my scars still feel quite raw! I had no real idea as to the date, but Google was very helpful.
Malone, it was a leap of faith if I remember rightly that just happened to land in the centre of the mat. A quite unusual happening I can assure you.
Deffo more of a wordsmith than a scientist, but fairly pathetic on that count too. Many thanks to all for the hand-holding when the LGCs fail the aged brain.
