Chinese Chess online (Xiangqi) I was curious about this question, I watched two videos and learned a bit about Chinese Chess. Where can one play it online? What site has the biggest online Chinese chess community, where  you can play against computers or challenge other players.

It must be free and and must support westernized pieces because I can't read Chinese characters. 

If the site has tutorials on the Chinese chess, it would be nice.
You can try PlayOK, it's free and has quite a lot of players for Xiangqi, and supports westernized pieces (though I'd recommend just learning the chinese characters, it doesn't take long). It also has some players for Shogi (japanese chess), which I personally find to be a much more interesting chess variant, though if you want to play more of that there are better sites (for example 81dojo). For rules/tutorials, I guess the best place to start is simply the Xiangqi Wikipedia entry.
