I have seemingly conquered DriveThruRPG/RPGNow and now CreateSpace, as I have an official preview sample being mailed to me after finally figuring out how to properly format the cover image for my print version of the book after more than a few rejected reviews.
Next on the plate, I am going for the Kindle formatting...since I started with a word document, this may be a bit easier than it seems.
Have not tried to deal with Lulu yet...that will happen after the Kindle.
The good news is that I am creating working templates that should make everything a bit easier going forward. Now if I just had some more money for original artwork...
