May slot 2 JISM, GISM.

[ROY TAYLOR]

I apparently lost a dot for slot 2 May for putting GISM instead of JISM. GISM is in Chambers as alternative , and fits the clue. i protest. Roy Taylor.

Oh really ?! I agree with you Roy.

GISM and JISM are interchangeable and 'exercise centre said' could just as easily give GIM as JIM.

Was there a stated reason why GISM was 'incorrect' ?

[ROY TAYLOR]

No reason. How do I officially protest this?

[zinzan]

You contact David Grainger and/or Ian Williams.

Whatever Chambers says, it pays to read any instructions to the puzzle, which were "Each answer begins with a different letter.". Taking GISM as the solution for 12-across gives two answers beginning with G, GISM and GENUINE, but no J. Sorry, no dot!
