The problem is that they all appear in the latest postings as "Puzzle" so that I click on the question only to find that I've already looked at it and I would be surprised if I am the only one to find that annoying.
The title of this one could be "Puzzle - 9x9 squares" or something like that, or if you can't really think of a couple of words to summarise the puzzle then simply start numbering them 1, 2, 3 and so on (but a brief description would be so much better).
