WordPress resources
There are a handful of sites I turn to when seeking WordPress guidance. These sites are incredibly useful for solving WordPress issues, finding plugins, and seeing site examples.
WordPress Codex
The WordPress Codex (http://codex.wordpress.org) serves as the "online manual" for WordPress, which continues to evolve and expand with the platform. The Codex is full of resources for both users and developers seeking to extend WordPress.
WordPress Support Forum
The WordPress Support Forum (http://wordpress.org/support/) is an effective way to learn from the large WordPress community. In the forums, users request assistance both regarding the WordPress core and specific plugin help.
WordPress Showcase: Education
The Education category of the WordPress Showcase (http://wordpress.org/showcase/tag/education/) serves as a gallery of education related to WordPress sites. This is a great way to get inspiration and see how others are utilizing WordPress in an education setting.
