A new website for machine learning software has been launched at http://mloss.org. Paralled to the efforts of JLMR, it is focussing on open source contributions:

"Open source tools have recently reached a level of maturity which makes them suitable for building large-scale real-world systems. At the same time, the field of machine learning has developed a large body of powerful learning algorithms for a wide range of applications. Inspired by similar efforts in bioinformatics (BOSC) or statistics (useR), our aim is to build a forum for open source software in machine learning."
