We have just added scoring to Weewar.com. So every time you defeat another player you get a number of points. If you lose, points are taken away. Everybody starts out at the same 1500 base level. The catch is: You get more points for winning against stronger players then for winning against lower ranking players.
Right now your current score only appears next to your user name during games. But once a few players had a chance to actually accumulate a few points (I am at 1560) we will look into rankings and public profiles next.
Let us know how scoring is working for you.
