One writer is selling research packs where the basic info is researched for you on a topic, you write from there. Nice idea. SueC
YES because you have double the work to do, by reading the book and rewriting it again... But if you were to make your own copy you can go to any direction you want! No limits or rules.
I prefer writing and researching my own. Whenever I have taken on projects rewriting PLR articles or eBooks or rewriting my own writing, I generally get bored quickly. I think half my enjoyment of writing is in the researching. I know I'm warped and twisted. LOL.
