The WP-Announcements plugin is ideal for websites or blogs that would like to display a site wide announcement, featured post, important message, community notice, advertisement, survey form, email subscription form, emergency alert or anything you can publish in a post as a marquee or popup window using ShadowBox-JS or ThickBox.
WP-Announcements provides two announcement options:
<ol>
<li>
A customizable marquee that displays an assigned post title linked to that actual post. The marquee can be displayed by calling the php function wp_announce_marquee(”) anywhere in your theme, using the WP-Announce-Marquee Widget or using the Shortcode [wp_announce_marquee] anywhere in your post or page content.
</li>
<li>
A popup window using ShadowBox-JS or ThickBox that displays the title and content of an assigned announcement post. The popup will only show up once for each website visitor per active popup post as a cookie is created. You can also set a popup window for each time a website member logs into the admin dashboard.
</li>
</ol>
WP-Announcements activates checkboxes on the add/edit post page to allow easy assignment of announcement posts. An admin page under the settings tab is also included to toggle announcements on or off and to manage all posts saved as announcements for easy retrieval and reuse of reoccurring announcements in the future.
Works with WordPress and WordPress MU 2.8.1
