Well, here's the update... after what Gillhoughly said, (did I spell his nickname correctly?) that the first publishing rights would be gone forever, no matter if I publish and then unpublished something, it's dead, and so I deleted all of the manuscripts I have published before, on Lulu, CreateSpace and Wordclay, and I didn't realize I had published so many, when I thought back and said, 'Oh, crap, I published this already...'
So now I have 11 manuscripts, 5 of which I've finished, that is written 80k words or close to that, and everything that's below 80k I consider unfinished, so yeah, that's what I did so far. I know that I could've made changes to the manuscripts and turn them into completely different novels, but for me, it's easier to just delete them completely and rewrite them from scratch, like I've done many other of my past novels, that is the novels that I've lost access to and could never finish, 10 years ago. As for the CD-R I just deleted the manuscript folder off it and saved the disc because I formatted it as a live-file system, meaning I formatted it like a USB flash drive where I could always add more files or delete files.
I thank everyone for your advice and now that my manuscripts are going to be 80-90k words, 90k if it's sci-fi, and no more than 90k, it's going to be easier for me to finish my unfinished manuscripts because most of them are +40k already, and if I was able to write a few 200k novels in the past, in less than two months in those cases, I'll be able to finish my unfinished novels and then write more. I will not query any of my finished novels until I finish my unfinished ones.
I love you guys very much, all of you, and I apologize if I've treated any of you unfairly.
Magali.
