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.
[Darren] Someone needs to do a good, solid corpus-based statistical study on activity rates in the Morniverse. I'm sure it would make a good PhD topic. My impression is also that activity has declined, but it was less busy than now when I first joined eight years ago (bloody hell, eight years). In those early days, fresh with the joy of discovery, i can remember having posted the last move in every game on York and MCiOS, and being quite at a loss for what to do next once I'd done it. Especially on weekends. In retrospect this was a bit rude, but I was immature and callow even in those days. :) I find that nowadays I tend only to post in a small subset of games and even when bored am unlikely to stray into the others. Maybe other people have gradually settled into a similar pattern.
