The most recent writeoff has just finished its writing phase as this post goes up, and I spent much of my weekend hashing out an entry. I have a lot to say about this story, but since basically everything I want to say would compromise its anonymity to one degree or another, it's just going to have to wait.
But you don't have to wait! If you're interested in reading a collection of stories based on the prompt "behind closed doors," the entries are available here. You can just skim through and find a few that interest you if you want, or you can tackle the lot (as I type this, three hours before the deadline, there have been 12 stories submitted; that number always grows in the final moments) and vote for your favorites. Also, don't forget to drop by the discussion thread to check out peoples' reviews and comments on the stories, or to offer up some of your own if the fancy strikes you. I'll hopefully be posting my own comments in that thread within the next few days, if that's the sort of thing you want to watch for.
