This is perhaps over-cautious, but I wouldn't want us to stray into the realm of revealing too much. The top/spare row and column seem quite important....
Gitto, I was concerned that a complete/corrected list of letters for the top row might be provided - and that could perhaps reveal too much. I don't think anything vital has yet been revealed!
Thanks,drxx. I did say I was perhaps being over-cautious . I was possibly worrying too much about all the letters (in that row) being revealed - but maybe no-one here would have given them anyway!
