I think it would be nice to show the number of games remaining in an ongoing match (as is done for tournaments) in place of the color-coded square symbolizing match in progress. The smiley faces indicating which clan won or lost are also very similar -- perhaps make them color-coded as well?
It might also be nice to show the clan record on the main page. I know it is available from list my clans, but why generate the extra page-loads (I, for one, belong to only one clan, and list my clans only when I want to see our record).
Great site. Keep up the good work.
