When I was in Germany, I didn't access my Facebook as I had to pay for the usage. But when I was in Holland, I could use the pc for free. When I tried to log in my Facebook, it was temporarily locked. I managed to unlock it anyway. Of course, there were some procedures to follow.
When I was in London, my Facebook was locked again!
I was asked to identify my friends. Well, that was easy..
No problem at all..
Then, I could return to my account!
Another problem I faced initailly was that I couldn't get the '@'.
It's an American keyboard.
I had to ask someone for help.
