I updated the ephemeris WordPress plugin. The new 2.0 version is a major upgrade. I checked compatibility with WordPress 2.8.2, integrated the Hungarian translation by Tamas Koos, added a new [ephemeris] shortcode and upgraded the code to the new WordPress 2.8 widget structure. You just have to put [ephemeris] in your posts or pages to have an embedded widget (see below). Get the ephemeris WordPress plugin.
