This is a tricky question. I know for a fact that I'm not finding any stories which appeal to me on many visits. My particular interest is in secret police dealing with female opponents stories and no one else appears to be writing these except Cortez, Electrosadist, Dom Master, Powerone and me.
Judging from the number of readers Cortez gets this topic does appeal but few people write. Is it because lots of people have a few ideas but can't string them together in a story? If that's the case perhaps we could set up some kind of trading centre for short extracts where people can send a little piece which they are happy for others to read or use.
The only way to get the stories you want is to write them I'm afraid.
As for the comment about stories not being updated I am one of the offenders there - I haven't had a chance to update the Colonel's Memoirs simply because I have too much work to do in my real life and haven't had the chance to sit down and write. I'm sure I'm not the only one of our authors to suffer this. There is also the case of 'The story that goes nowhere' where you start with a chapter, post it and then find you can't develop it to your own satisfaction. I did this with 'El Alacran' - should I have posted it or not? Well I know some people enjoyed it so if I hadn't they would have missed that.
