I did take part, and managed to do what I usually manage to do. Rather than pacing myself and writing a little every day, I got a little carried away and finished my story on Day 10.
But the other part of it is I have no life. Generally any time I'm not working I spend at home, either gaming, or pootling about on the computer. So writing a story in 10 days seems........ relatively easy :)
I'm going to leave the community open (sorry -- couldn't remember if it was a thread, sub, space or what for a moment -- far too many message boards!!), although I think it will get very little use before October next year, but you never know -- people might want to write advanced plots or do games and such.
