The season is just ending in the northern hemisphere. But there is the Heineken Cup final this Saturday (which is the European championship final of rugby, I'm going

) that promises to be an awesome game with Munster v Toulouse. I guess it's in season in the Southern Hemisphere, so try and check that out. I'm not really knowledgable on stuff down there though. Bad Company could help you out I'm sure

.
If you had one of the Rugby video games, there's a great Rugby 101 video, basically explaining the complete rules of rugby to a total beginner. Dunno if that's online or anything though. You could probably find something similar.
