I think there is a typo on this page. The tab says, "Top 20 Member Rank" but results for 50 members are shown. I really like your site, so I consider this message to be a contribution (however tiny) for what it's worth. By no means is this meant to be a dig (those are always much wordier).
I wouldn't expect to see the rankings of every last member, but I was hoping that the "Search" tab would give my results with its ranking. If this isn't already a feature that I'm simply overlooking, could you consider this as a feature request?
Thanks, and my compliments to your site.
