what makes you believe .com.cn is not a sub domain? Besides folks in the UK, know a good name when they see one. I'd rather own a .cc or .ws, before a .com.cn. The ".org " in UK is just like ".org " for organization. I think the name makes sense, if you are an organization in the UK that is Track related. Hence the name " Track.org.uk" make sense? Just my opinion!
