I'm taking part in NaBlo for the second, but hey! I'm not American. I'm a South African living in Germany and there are many other global bloggers also participating.
Let's consider a name change for next year. How about GloBloPoMo (my favourite) or IntBloPoMo (coined by (Un)Relaxeddad at http://relaxedparents.com).
Ooooh I like the sound of GloBloPoMo because this sounds easier to remember than NaBloPoMo...I have so far always had to think of what it means in full and then work backwards to the abbreviation :=( GloBloPoMo rolls off the tongue much easier too.
I'm one of the non-USA bloggers too, living in Amsterdam in The Netherlands, so hello to all the other non-USA bloggers taking part in this this month.
