WP Sessions is a long-running paid video-tutorial site for WordPress developers founded by Brian Richards. The catalog is more focused on the building side of WordPress (plugin and theme development, custom workflows, the underlying PHP and JavaScript) than on the user / site-builder side that most generic WordPress tutorials cover.
The CourseFlix listing carries Your First WordPress Plugin from the WP Sessions catalog. Material is paid and aimed at developers who already know PHP and want to build custom WordPress functionality rather than configure existing plugins.
