Communication via messaging.

I used Facebook mail to keep in touch with family members across the globe, I prefer using Facebook messaging over email, for example because my family can reach me anytime as Facebook is delivered straight to my phone, IPad and iPod. I prefer to use Facebook messaging over email because then you can tell if the message has been 'seen'. The new 'seen at X o'clock' feature is handy for me as my family and I have different time zones, and it shows when they will or will not reply immediately.
