You can hover over Members at the top of the page and the last one on the list is Member Map.
I have only 10 minutes experience with it and its great except for two things.
1) If you do not feel like publishing where you live, you can look at the member map, but don't add yourself to it. You have to manually add yourself to it.
2)I have a high-speed internet connection and the webpage was still bit slow.
Check it out!!!!
