vents Manager Extended (EME) is a fork (NOT an extension) of the older Events Manager (EM) version 2.2.2 (April 2010). After months, the original plugin came back to life with a new codebase, but I added so much features already that it is very hard to go back to being one plugin. Read here for the differences since 2.2.2: http://www.e-dynamics.be/wordpress/?page_id=2 Events Manager Extended integrates with Google Maps; thanks the geocoding, Events Manager Extended can find the location of your events, and accordingly display a map.
Events Manager Extended provides also a RSS and ICAL feed.
