Ok You see a link to "Map" on the navigation bar at the top. It's a big map with markers for each member. To add your marker, you will need to find out your lattitude and longitude.
Here's how to do that:
Go to:
http://www.maporama.com
Input your address and map it.
On the left column, there will be an "Information" section with your Lat and Long. The 2 numbers on the second line are the ones you input.
