Oldman: Don't know if you considered this and you probably already know about it, but apparently www.lulu.com (I'm not associated with it) is a great place to self-publish. My friend is writing a comedy/commentary styled book and is going through them. Apparently for awhile now, they are offering the ability to purchase an ISBN number and they handle the distribution to Amazon.Com, Barnes & Nobles, Borders, and any book store that buys their books from the massive wholesaler, Ingrams. I've signed up for an account for test purposes, and it seems a bit easy. Make a .pdf of the book, upload cover art and you're good to go!

Good luck and can't wait to get a look at the book.

EDIT: By the way, it's completely free. Lulu takes a commission out of the sale price that's actually not too bad.

Thats pretty cool. FightingArts also does some publishing. Id like to have the time to write. I wish you the Best of luck Mark, and look forward to seeing the final draft.
