I'm always aware of security and privacy issues on Facebook, so in case any of you use Facebook and didn't know about this, I'm posting it here.
Facebook launched Facebook Places yesterday. 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 maybe it's a good idea to post the above on your Facebook status, as I have. It doesn't concern me on a personal level, because of where I live, but I do worry about all the young kids using Facebook, who may well be on their computers at home alone. So please make your kids aware!
ETA: I would mention that the above was copied from one of my Facebook friends' status...someone who is trustworthy... so I'm passing this on in good faith, without being able to check the accuracy. But I thought it better to be safe than sorry.
