Now there is a ladder for your Warhammer 40k Module games on Vassal.
You only have to register and join the ladder and can report every game against other ladder members then:

Warhammer 40k Module online matches ladder

It would be also possible to put up more ladders, like a special Warseer only ladder or sometimes a Forum ladder to find out which forum fields the best players.

I hope you enjoy it.

In case you dont know the Warhammer 40k Module at all:
