ABCD (2) (Posted on 2008-03-07) Difficulty: 3 of 5
Place one of the four letters A, B, C or D in each of the blue-coloured cells. No letter can be horizontally or vertically adjacent to itself. The yellow-coloured tables above and to the left of the grid indicate how many times each letter appears in that column or row.

This is an extended version of ABCD.

Dej Mar, I realised that after posting but didn't worry too much about it.  Another thing I noticed that at the moment, this being the "Problem of the Day" it does not have the rating scale showing until you open the comments.

Interestingly if you open any of the problems below it, that problem opens with the comments list and the rating scale displayed.

I'll take that a step further. 
If you open any of the categories at the top of the home page, the first problem of that category always seems to display without the ratings line while puzzles opened down the list open as noted above, a comment list is published and he rating line is apparent.
