[Inkspot] Having to reproduce that grid each time kills the game instantly. It would be an utter pain in the arse to edit that each time a word was added (and when does it get updated? after every guess? each new word?), and the chance of screwing it up would be very high. (Note how many mistakes have been made just counting backwards in the Celerity CDs game! And note how hard it is to get certain participants to realise they've been getting the rules wrong.)
If you want a cryptic crossword clue guessing game, I'd strongly recommend doing it as was done before, with people submitting and guessing clues as they felt like it, with no grid.
I think, incidentally, activity on all three sites was waning even before the Orange festival, although that has made it more obvious. We're just not getting the same number of participants these days.
I agree with your points about the problems of updating and my greatest fear of solutions not fitting previuos moves and having to be redone. But I needed feedback like that so as not to make a complete prat of myself by just setting up the game with all of it's woolley thinking. There are other types of cryptic games already played on this server, but I wanted one that had a finite life span. There is still an empty game slot.
