On the top performers page you have spelled Performers wrong in the H4 tag.
Also I think that the start date should automatically clamp to the first of the month.
Also it would be good to have a date picker like the one from ajax control toolkit?
I have been using this site a lot over the last few weeks and I have noticed a few inconsistencies. Would anyone be interested in me posting these up when I see them or am I just being picky?
