This is great information to give you the option of using this Facebook tool. I felt it was tooinvasive and turned it off. Just read and follow the directions below:
Anyone can find out where you are when you are logged in.
It gives the actual address & map location of where you are as you use Facebook!! Make sure your kids know. TO UNDO: go to "Account", "Account Settings", "Notifications", then scroll ...down to "Places" and uncheck the 2 boxes.... Make sure to SAVE changes and re-post this.
THIS IS AS MUCH ABOUT SAFETY AS ABOUT ANYTHING!
