Austin Passy is a WordPress developer in California and a tutorial blogger at WP Wag. Over the weekend Passy created and released a new WordPress plugin over the weekend called “Hellos Bar” that adds announcements to WordPress sites using custom post types.
Passy describes just how the plugin operates on his blog:
Adding a post to the CPT
hellobar, and activating the plugin in the settings page will insert one random post from the post list in a fixed position at the top of the browser screen. Using jQuery the bar will drop down after about 5 seconds.
