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.

While Josie does have one it is her perogative when she makes it public.  Many authors like to hold off for a week, some will do it within a day or two.  In the case of students a scholar has to be done by a scholar or levik.  If we miss however, when the student becomes an apprentice then that person can make the posting.
