Have you heard about Leanne King? If you want to learn how to use WordPress in your internet marketing endeavours and to make money online, Leanne is the right person to learn from.
She is well-known as a WordPress Queen and she is an undeniable WordPress expert.
I know her from a private Internet Marketing Forum run by James Schramko where she solves all the issues, answers all the questions and gives great tips and advice on WordPress.
Quite often I visit also her valuable blog for more great info.
She is also the author of an e-book called "WordPress for Internet Marketers" or WordPress Bible, which I bought shortly after I got to know her.
What I find extremely useful is that there is enough information for both amateurs and advanced WP users.
After reading her e-book as a beginner, I continued to go back to it even as I progressed to the advanced level of operating WordPress.
This e-book consists of 899 pages and it is the largest single source on WordPress on the market! It is a thorough approach to various aspects of WordPress and its significant role in internet marketing.
From the Bible, you can easily learn how to use WordPress and in particular about:

• How to install WordPress step by step, using hosting services provided by Hostgator, which I use myself and strongly recommend
• Interesting themes and skins, favicons, plugins
• Creating posts and the design of a website
• Amazon, eBay on WordPress - how to make it work
• Clickbank and Commission Junction in relation with WP
• How to create article directories
• Creating e-stores, using Magento for example
• Creating Forums
• RSS and SEO

These are only some of the issues described in this e-book.
The great thing is that apart from the written information and useful links, Leanne put an amazing amount of screenshots to show how to install and implement various solutions she writes about.
