How about adding a Row to the Board Information table of a Board Info page that displays the #1 Ranked Player of the Board. Would be kinda cool I think.
"But many who are first will be last, and many who are last will be first." Matthew 19:30 - Good strategy for life and WarGear!
+1 on it being cool.
A related idea (that could go into the achievement system) would be to have a place on a player's profile that displays the board image's of the boards a player is #1 on.
Both good ideas have added to the list thanks.
