hmm...sorry for the late reply, didnt notice your post until now:$
there are a few surnames that are dominant over here such as Lee, Tan, and my own Lim etc but there are also other less common ones such as Quek, Lau and Chin etc. it should be noted that the surname dominance in singapore is a little different from that in China as most chinese in singapore comes from the hokkien islands (may contain spelling errors) and thus our surnames are similiar to people from that region of china while the prevelence of other surnames from other parts of china makes them (the others) the dominant ones in china, hence the difference.
and of course in singapore there are malays, indians and many other races but the chinese are still the majority here
btw the "ETA" in the ACARS table at the main page should be "ETE" instead
also, the roster does not remain sorted eg by hours when you switch to another page of the roster
