hmmm... I will have to look into the options there. I know I can turn the big map into a members only page, and you can turn your profile to members/friends only. Not sure about setting that for the individual map settings for each user.
When I built that, I did think about privacy, which is why I put the Zip Code option in there. Thought it would get people to the neighborhood, but not to the spot.
I will see what I can find. Thanks for the suggestion!
