Did I publish too soon?
This is my first Lulu (or any, for that matter) book. Using the creation wizard, I went through all the steps, hoping to get to a point where I could order a print copy for a closer review (I think some things might show up better reading it that way than reading it in Adobe, etc.). But I just kept going through the wizard all the way through the "Publish" step, making the Lulu listing visible only to myself. I then ordered a copy at my cost, which actually surprised me for how cheap it was.
So if I get my copy and then find some things that I want to change before making the listing public, am I free to go back to the steps where I upload my PDF file, etc.? Will this constitute a "new edition"? Will anything else have to be changed?
