to answer the idea question in the other thread.
I get my ideas from a lot of places, movies, books, cartoons, people I see on the street, discussions in forums and I jot down the ideas in word, maybe a first chapter, save them, file them and when I'm looking for a story I open the folder and reread.
As for editing, I tend to edit as I write and skim over it when I'm done. If it's a story that I am holding chapters back (rarely do) then I may reread it a couple of times otherwise I post it after I finish.
