Users can create and edit their own POIs but can't edit those created by others unless they have sufficient privileges.
POIs are stored in the database on a per-placement basis: different instances of the tool on the same server each have their own collection of POIs.
The site maintainer can define POI types, which are shown in different colors on the map. Users can filter the POIs on the map by type so that only POIs of a certain type are shown.
Maintainers can define up to three different maps (a point and zoom level) that users can navigate to easily.
Future plans include integration with the wiki tool: user will be able to select a wiki page as link for a POI.
