Yep I have to agree with Boccaccio - you can't change things once you've submitted them and if your ideas evolve as mine do it would take an absloute age before I could publish anything. It takes me a long time to get my ideas actually written down anyway - not necessarily because they are complicated or anything but just the fact that I'm slow at writing.

Getting a little bit of feedback now and then really helps. As was said earlier in the thread - if you submit the whole story in one hit you get one chance at people taking the time to comment. Adding chapters creates many more comments. I also find that people mail me with ideas as well, as the story progresses, which all helps.

It also lets you know if your story is actually arousing i.e. you've got it right! Not that that may be important to some authors - but it is to me.
