Oh no, there's a new member again!!

Hello Everybody,
I am a new member of this forum, my English is poor and I need to improve it, that’s why I join this forum. Moreover it always be nice to have new friends from all over the world.

First, let me introduce myself. My name is Widhi Ariandoko, you can call me Widhi, Ariandoko or just simply Ndoko. Neither Widhi nor Ariandoko is my family name. In fact I don’t have family name. Weird, isn’t it? But it’s normal not to have family name in my place. About my ethnicity and my nationality? Umm, can anyone guess them by looking at my profile picture?
