In order to supplement the Smashwords Style Guide, I have updated the tutorial (with videos of my goofy voice) to help indie authors looking to get their work self-published on Smashwords. It is advantageous to go with the Smashwords option, since they distribute to other markets and function as a vendor to online shoppers. The royalties are attractive for the self-publisher, and you have much greater control over coupons, contests, and other goodies compared to the Amazon.com Kindle store or the Barnes & Noble NOOK.
The problem with Smashwords is that the Meatgrinder is a major pain in the rear. This is their system that convert a Microsoft Word .doc file to EPUB, MOBI, PDF, and other formats. It also doesn't help that you can't test the Meatgrinder until you actually update your file to Smashwords.
This tutorial on getting a bullet-proof .doc file to convert into eBook formats through the Smashwords Meatgrinder will hopefully be useful for all us indie authors out there. Good luck selling your eBooks!
