I have started a Rugby World Cup prediction pool on www.superbru.com and given it the name PomsinAdelaide. Its free to join and is a great way to add a little spice to following your team through the World Cup. Just sign up, look up the pool by the name and enter the pool code woldslum.
Hopefully come finals and semi finals we could organise to watch a few games socially. If the above does not work for you, send me an email on firstname.lastname@example.org and I will send you an automatic invite to join the fun!
