Hi, Rossim!
How are you?
Thank you for that - yes, I did know about it but only learnt of it on Tuesday when chrise told me of it.
I shall study it today to see where I fell down on yesterday's crossword! (I found it much harder than my first attempt the day before!)
As it gives ALL the answers though, you can expect to see me asking for help on here if needed 'en route' so to speak ( the trouble with looking up one answer on a site like that, you inadvertently see other answers too!
but it will be great to learn from, when I've given up!
