Olichant, I can't recommend it highly enough. For an annual subscription of £35 (you can buy part years) you receive, in a single email sending just before the month begins, six crosswords a month (that's slightly cheaper than the Listener Times Crossword Club price). The puzzles are rated in difficulty from A to E with a C puzzle being about average Listener difficulty. Obviously you solve them when you like and can submit them if you wish (with three Magpie pens as prizes - but which of us needs another BRB anyway?) There is a record kept of solvers' performances with a league of brilliant solvers who get them all right (I really don't know how!)
One puzzle is numerical - it's by Googly this month.
The A (easier than Listener) is by Chalicea
The B is by Nutmeg (great fun)
There is a C by 'INCOGNITO' (we have to work out who the compiler is)
There are Ds by Mr Magoo (he's the Times crossword champion and one of the editors) and Pointer.
The editorial is always good reading and the layout is a work of art.
