Hi Al and welcome.
A note though... you might want to consider publishing on other sites and in other formats to reach a much larger audience. I don't own a Kindle, so can't get a copy of your books, and that's a pity because they sound really interesting. Also, Kindle is currently US only so a lot of readers outside the US can't get it.
Maybe you could consider publishing on Smashwords. If you like, here are a couple links that other authors found useful:

I look forward to being able to download and enjoy your books.
