Yesterday was also my birthday. Outside of my family, only 3 friends remembered. My best friend since primary school didn't even remember. So that was an interesting side effect.
Now, after some searching, it seems in some countries you can use FB messenger without a FB account, just a phone number and name. One being australia. This was announced on december of 2012 I believe, but I haven't seen anything since. Theres nothing online about how to use this outside of the 5 countries, so does anyone have any info about this? Because I still want to stay in touch with a few people and FB messenger is still the easiest for everyone i usually talk to.
