It's been a while since we've discussed avatars. I'll go first:

Avatar: Angie (current photo of me)

Name: Angie 

Real Name: Angélique

People in the US call me Angie, and so did/does my late Mum, Dad, brother and parents-in-law. My parents and brother pronounce it the Dutch way though, which sounds more like "Un-chee". When Greg refers to me in conversation, he calls me Angie. 

My school friends, university friends, both sisters-in-law, nephew, all my Dutch relatives and friends, most Euro friends, and friends in Hong Kong, call me Angélique. And when we lived in France - most called me by my full French name. 

I go by both names, but Angie is MUCH easier to remember and spell, so that's how I introduce myself in the US.  

Over to you. Where does your avatar name come from?
