Some scikit-learn regular developers will attend the SciPy 2013 sprint, so it's a good opportunity to discover the scikit-learn contribution workflow.
Potential work include:
test and review and merge active pull requests: https://github.com/scikit-learn/scikit-learn/pulls
finish full Python 3 support
work on better parallel support in joblib (shared memory with multiprocessing or add multi-threading support to joblib when code is able to release the GIL in pure cython CPU intensive functions)
