The template provided insufficient, so I made my own. This is by no means a definitive explanation, but its an attempt.

The enhancement idea is to implement heads to match the name of the player on the sign (Very much like how BuyCraft Heads work)

I am no java dev/expert, but the concept is to have the sign placed down search for a head block around it (on sign create) and put the players head on it and then update whenever the stats change.

Also, look to this ticket for PV tracking information which can be combined with OnSign to create signs that show the
%top
player in the requisite daily/weekly/monthly/total time ranges for pvpkdr/pvekdr/pvpkills/pvpdeaths/pvekills/pvedeaths
