No not really, you'd have to goto each individual league site (but even some leagues don't post results :tired: ).
But... what you ask here is a damned good idea... would be really neat to see results from all kinds of leagues, both large and small ones.
For now, LFS-News has a few league's results listed, but nothing that is easily found, its all over the place per each league's own news (on the left menu).
