Facebook?
I'm a regular user of facebook because i find it's a good way to keep up with mates all around the country as a result of being in the air force.
However, i've recently found out i'm going somewhere hot and sandy for the rest of the winter and someone mentioned that it was a bad idea to be on there (and also a bad idea if you haven't done the A course yet) because people can potentially find out too much about you.
Is it such a bad idea or can you do things to make it as safe as possible?
