I also had a couple of questions about publishing.  If I release my game as a pdf, what services can I use to distribute it, and how do I connect with them?  Can I use RPGNow, Indie Press Revolution, DriveThruRPG?  And, later on, what if I want to release my book in print form?

To distribute a PDF version of the game, you're probably best off selling it directly from your site.  There are folks here who can help you through setting up an ecommerce site for games.  I have set up ecommerce for downloadable software, and the principals generally translate pretty well.  Contact me privately if you want my help.

You might ask about the RPG Bookshelf, too.  Not sure how that is managed, but I know a few people have used it and liked it.

  Thanks.  I'll message you when I get ready to distribute, however long that'll be.
