By the way, I managed to get the first public result with nnForge: The 3rd place in Challenges in Representation Learning: Facial Expression Recognition Challenge at Kaggle.
This contest and two others were the base for the ICML 2013 Workshop on Challenges in Representation Learning, all the results are well covered and analyzed in "Challenges in Representation Learning: A report on three machine learning contests", Ian Goodfellow et al, arXiv:1307.0414.
