The definitive source for WordPress information. WP’s own site gives you access to the latest version, themes, plugins, support forum, and tons of documentation.
StudioPress Genesis Framework Themes
Start with one of the free WP themes you can install from within WordPress. But if you can’t find one that suits your needs, or if you’re ready to move up to a premium theme, try the Genesis Framework from StudioPress.

While there are a number of conferences you can attend to learn more about WordPress, there are also quite a few user groups around the world and you can usually find one close to your area. Many of these user groups also put together WordCamp events where you can network and attend some great informative educational sessions.
