Here is a contest based community called CrowdANALYTIX.com which is quite nice and offers you free Revolution R for the statistical and analytical contests based there (a bit like Kaggle.com http://www.kaggle.com/). There are only 3 contests right now and that too low volume but I guess that number should increase. Also they seem to have a consulting arm.
