I have a story already posted on PD that has seen quite a few hits. It's working name is Lioness. But I've known for awhile that it needs improvement. Well, I went through and added a lot more to the beginning of the story to make it more meaningful and understandable. Now that I'm almost ready to post it to PD, I realized that I don't exactly know how I should go about it. Should I start a brand new submission with all of the new and current parts, or should I go through and do MAJOR editing to the already existing story (in effect changing every chapter already posted)? Which would be better or is there another option?
