In this presentation (pdf) which was given in Brazil, September 2011, a short description is given how to use the website.

Use the "MAP" menu item on the main menu and locate the location to be edited on the map. By clicking on the point in the map, the information of the location is shown. If you are the owner of the point (you have uploaded the point while being logged as the same user) you will see an "edit" tab on top of the page. If you click on this edit tab, you come into the "UPLOAD YOUR DATA" mode for the selected point, and you may alter the information which you have entered and/or add other relevant information.

Uploading of a location is only possible if you log in to the site. If you are logged in, you should be able to see the  "UPLOAD YOUR DATA" item in the main menu bar (blue).

It is also possible to manually enter coordinates in the WKT field, just by displaying the WKT field, and edit the longitude and latitude values (e.g. GEOMETRYCOLLECTION(POINT(33.242654800415 49.615381488303))).

Click on MAP on the main menu bar (blue). By default, the site shows a map of Europe. All sites are plotted on the map, but if they are closely together the locations are clustered to one location.
