We have volunteered to work on a website for the Earth Day 2010. Our partnering client was eco-friendly NGO 'Green Wave".
The site had following user facing features to facilitate creation of content:
- create public group and let visitors join and subscribe to group news
- add events to the calendar
- select location on city maps where event was going to happen
- export events via GeoRSS to display maps with events on the group's blog (read more at http://www.digitalist.com.ua/2010/04/16/intehracija-kart-v-wordpress-eksport-v-georss/ )
