Many features have been included in the page in the last months. I know that any of them has represented a lot of work, however I suggest a new feature: Since actually the puzzle id number is shown on the page, would it be possible to provide a link to access to, using that id (or/and via the date and size/level of puzzle) any of the old and past puzzles? (actually only 7 days can be seen). In this way, the members of the forum could use them as examples, to discuss techniques or strategies (new people coming to an old topic could have a possibility of knowing what has been talked about just by calling that puzzle on the screen and with the option of printing it, etc.) (That access, if necessary, could be restricted to only registered members of the Calcudoku page).
