First notebook entry: Introducing myself

I am from Shanxi province in P.R. china. I want to study English very much by italki.com. It is nice to meet everyone.

I completely understand what you wrote, but I am just being critical. While it is socially acceptable to put "nice to meet everyone", it is not grammatically correct (Of course everyone will understand you, but someone will eventually get onto you about it). Don't foget to properly put a verb into the subject of your sentence, in this case, "is".
