[edit] How to add a map

To add a map simply add a code like this to the content:

<Map>0|0|17|300|300|http://www.canoepolo.org/|CanoePolo.org|</Map>

Each data is separated by the "|" character.

• The first 2, 0|0 is the latitude and longitude
• Next, 17 is the zoom level. 0 is the max zoom
• 300|300 is the width and height of the map
• http://www.canoepolo.org/|CanoePolo.org is a link when click on the location
