OblivionageCaptainZidgeltf2pl.com has gained some traction in the month it's been open. It's pretty good.
it thinks i don't have the game. are there any other sites?just had to relog on the site and it detected it.
edit: how do the rankings work? what is beginner, amateur, advanced translate to in esea or ugc?
It's a pretty simple elo system. Wins gain elo, losses lose them. I don't think it accounts for expected winners/losers when changing elo. I'd guess Beginner is like iron/steel, amateur is high steel-silver, advanced is like silver or platinum.
